## Title
Conformationally constrained, fully synthetic macrocyclic compounds

## Abstract

Conformationally restricted, spatially defined 12-30 membered macrocyclic ring systems of type (I) are constituted by three distinct building blocks: an aromatic template a, a conformation modulator b and a spacer moiety c as detailed in the description and the claims. Macrocycles of type (I) are readily manufactured by parallel synthesis or combinatorial chemistry. They are designed to interact with specific biological targets. In particular, they show agonistic or antagonistic activity on the motilin receptor (MR receptor), on the serotonin receptor of subtype 5-HT2B (5-HT2B receptor), and on the prostaglandin F2•receptor (FP receptor). They are thus potentially useful for the treatment of hypomotility disorders of the gastrointestinal tract such as diabetic gastroparesis and constipation type irritable bowl syndrome; of CNS related diseases like migraine, schizophrenia, psychosis or depression; of ocular hypertension such as associated with glaucoma and preterm labour.

## Background
Macrocyclic natural and synthetic products have played a crucial role in the development of new drugs, especially as anti-infectives (see Review: F. von Nussbaum, M. Brands, B. Hinzen, S. Weigand, D. Häbich, Angew. Chem. Int. Ed. Engl. 2006, 45, 5072-5129; D. Obrecht, J. A. Robinson, F. Bernardini, C. Bisang, S. J. DeMarco, K. Moehle, F. O. Gombert, Curr. Med. Chem. 2009, 16, 42-65), as anti-cancer drugs and in other therapeutic areas (C. E. Ballard, H. Yu, B. Wang, Curr. Med. Chem. 2002, 9, 471-498; F. Sarabia, S. Chammaa, A. S. Ruiz, L. M. Ortiz, F. J. Herrera, Curr. Med. Chem. 2004, 11, 1309-1332). They often display remarkable biological activities, and many macrocycles or their derivatives have been successfully developed into drugs (L. A. Wessjohann, E. Ruijter, D. Garcia-Rivera, W. Brandt, Mol. Divers. 2005, 9, 171-186; D. J. Newman, G. M. Gragg, K. M. Snader, J. Nat. Prod. 2003, 66, 1022-1037). The chemical diversity of macrocyclic natural products is immense and provides a tremendous source of inspiration for drug design.
Macrocyclic natural and synthetic products generally exhibit semi-rigid backbone conformations placing appended substituents in well-defined positions in space. Certain ring sizes are preferred (L. A. Wessjohann, E. Ruijter, D. Garcia-Rivera, W. Brandt, Mol. Divers. 2005, 9, 171-186), e.g. 16-membered rings are frequently found in oxygen-containing macrocycles, such as polyketides (M. Q. Zhang, B. Wilkinson, Curr. Opin. Biotechnol. 2007, 18, 478-488). It is hypothesized that the semi-rigid scaffolds may possess some of the favorable binding properties of rigid molecules (entropy), yet still retaining enough flexibility to adapt suitable conformations in the binding event (induced fit).
Macrocyclic natural and synthetic products are generally classified according to the chemical nature of the backbone, e.g. cyclic peptides (Y. Hamady, T. Shioiri, Chem. Rev. 2005, 105, 4441-4482; N.-H. Tan, J. Zhou, Chem. Rev. 2006, 106, 840-895); cyclic depsipeptides (F. Sarabia, S. Chammaa, A. S. Ruiz, L. M. Ortiz, F. J. Herrera, Curr. Med. Chem. 2004, 11, 1309-1332); macrocyclic lactones (macrolactones) and macrolides; macrocyclic lactams, macrocyclic amines, macrocyclic ethers, macrocyclic ureas and urethanes, and others. The conformational, physico-chemical, pharmacological and pharmacodynamic properties of macrocyclic natural and synthetic compounds depend largely on the ring size, the chemical nature of the backbone, and of appended groups (L. A. Wessjohann, E. Ruijter, D. Garcia-Rivera, W. Brandt, Mol. Divers. 2005, 9, 171-186). By modifying these three parameters nature has generated a virtually unlimited repertoire of molecular diversity. Despite their undisputed interesting biological properties, natural products show some limitations for drug development, such as:

    
    
        High structural complexity
        Metabolic instability
        Low oral bioavailability
        Low membrane permeability; intracellular targets not amenable
        Low tissue penetration
        Short half-life
        Chemical synthesis often very complex and lengthy
        Often accessible only by fermentation or recombinant methods
        High production costs
        Complex QC and development processes.
    
    


Broadly speeking, the present invention describes novel, fully synthetic, macrocyclic natural product-like molecules of type I, which can be synthesized e.g. by connecting suitably protected building blocks A, B, and C in a modular fashion to a linear precursor followed by subsequent cyclization (Scheme 1).




Building blocks A serve as conformation-inducing templates and are based on appropriately substituted (R1) and protected phenolic or thiophenolic aromatic carboxylic acids.
Building blocks B are appropriately substituted (R2, R3) and protected tertiary amino alcohols, preferably derived from an amino acid such as substituted proline, substituted pipecolic acid or substituted piperazine-2-carboxylic acid. Building blocks B are linked to building block A via an ether (X═O) or thioether (X═S) bond and to building block C via a secondary or tertiary amide bond. The sulfur atom of a thioether linkage can easily and selectively be oxidized to the corresponding sulfoxide (S═O) or sulfone (S(═O)2) which forms part of the invention. Importantly, the amide bond between modulator B and spacer C can also be part of an extended connector moiety U. For example in the case of a standard amide bond, U corresponds to a carbonyl group (—C(═O)—). If U is defined as a carbamoyl moiety (—NR4—C(═O)—) the functional connection between B and C corresponds to a urea moiety. Similarly a carboxyl group (—O—C(═O)—) as U describes a carbamate linkage between B and C. In addition, U can represent an oxalyl group (—C(═O)—C(═O)—) or the corresponding acetal) (—C(—OR20)2—C(═O)—).
Importantly, in the case that R2 of building block B constitutes an amine substituent, an alternative incorporation into the macrocyclic ring via the exocyclic amine functionality is possible:




This alternative binding mode is also part of the invention.
Building blocks B serve as a conformational modulator by influencing the conformation of the macrocycle through cis/trans-isomerization of the amide bond.
In molecules of type I the building blocks A and B are connected via the bridges C; the structural element C is linked to A by a secondary or tertiary amide bond. The bridge C can be constituted by one to three appropriately and independently substituted (R4-R10; R14-17) subunits c1-c3 derived from suitably substituted and protected precursors, most often from, but not limited to, appropriately substituted and protected amino acid derivatives or suitably substituted and protected amine derivatives.




These subunits c1-c3 are in turn independently connected to each other by an amide bond (—C(═O)NR4—), a methylene-heteroatom linkage (—CHR3—Z—), an alkene[1,2]diyl moiety (—CHR12═CHR13—), introduced by olefin metathesis, an alkane[1,2]diyl spacer (—CHR12—CHR13—), accessible from the metathesis product by hydrogenation, an oxalyl group (—C(═O)—C(═O)—) or a disulfide bridge (—S—S—).
The spatial orientation of the substituents R1-R13 in compounds of type I is modulated by the ring size and the stereochemical connectivity within building blocks A, B and C. Both, the macrocyclic backbone and the substituents R1-R13 can contribute to the biological activity of compounds of type I.
The backbone of the compounds of type I is composed of an aromatic ether/thioether linkage and one or more tertiary amide bonds; in some cases an aliphatic ether linkage, an ethylidene or an ethylene moiety may also be part of the backbone as defined above. Ether linkages in macrocyclic molecules have been shown to be beneficial by favorably influencing physico-chemical and pharmacological properties, such as e.g. solubility in water, metabolic stability towards proteolytic degradation, cell permeability and oral absorption (K. X. Chen et al., J. Med. Chem. 2006, 49, 995-1005). In addition, tertiary amide containing macrocycles show increased proteolytic stability, cell permeability and oral bioavailability compared to the parent molecules with secondary amide bonds (E. Biron, J. Chatterjee, O. Ovadia, D. Langenegger, J. Brueggen, D. Hoyer, H. A. Schmid, R. Jelinek, C. Gilon, A. Hoffmann, H. Kessler, Angew. Chem. Int. Ed. 2008, 47, 1-6; J. Chatterjee, O. Ovadia, G. Zahn, L. Marinelli, A. Hoffmann, C. Gilon, H. Kessler, J. Med. Chem. 2007, 50, 5878-5881). For example, the cyclic undecapeptide cyclosporin A (INN: Ciclosporin), which is used as immunosuppressant in organ transplants, contains seven N-methylated amino acids and possesses good oral bioavailability when formulated appropriately (P. R. Beauchesne, N. S. C. Chung, K. M. Wasan, Drug Develop. Ind. Pharm. 2007, 33, 211-220). Peptidyl cis/trans isomerization of proline and pipecolic acid containing polypeptides and proteins is a well known process in protein folding events. In vivo, this process can be mediated by peptidyl prolyl cis/trans isomerases such as the cyclophilins, the FK506-binding proteins and the parvulins (A. Bell, P. Monaghan, A. P. Page, Int. J. Parasitol. 2006, 36, 261-276). Besides their role in protein folding and in the immune system, peptidyl prolyl cis/trans isomerases have been implicated in cell cycle control (P. E. Shaw, EMBO Reports 2002, 3, 521-526) and therefore constitute interesting pharmaceutical targets. FK506 and cyclosporin A which bind to the FK506-binding protein and cyclophilins, respectively, are both macrocyclic natural products, with the former one containing a pipecolic acid residue.
For many existing and emerging biological targets it is difficult to find classical small molecule hits as starting points for drug development (J. A. Robinson, S. DeMarco, F. Gombert, K. Moehle, D. Obrecht, Drug Disc. Today 2008, 13, 944-951). Many of these extra- and intracellular “difficult targets” involve protein-protein interactions, such as receptor tyrosine kinases, growth factor receptors, transcriptional activators/transcription factors, chaperones, and others. For several of them macrocyclic natural and synthetic compounds have been described as good starting points for drug discovery programs (e.g. D. Obrecht, J. A. Robinson, F. Bernardini, C. Bisang, S. J. DeMarco, K. Moehle, F. O. Gombert, Curr. Med. Chem. 2009, 16, 42-65).
The novel and fully synthetic macrocyclic compounds of type I described in this invention combine unique features of macrocyclic natural products with beneficial physico-chemical and pharmacological properties of traditional small molecules, like:

    
    
        Natural product-like structural complexity
        Good solubility
        High metabolic stability
        Improved oral bioavailability
        Improved membrane permeability
        Extra- and intracellular targets amenable
        Improved tissue penetration
        Small molecule-like pharmacokinetics
        Modular chemical synthesis
        Synthesis process amenable to parallelization
        Reasonable production costs
        Small molecule-like QC and development processes
    
    


More particularly, the present invention provides macrocyclic compounds of the general formula I (Figure 2), which are comprised of building blocks of general formulae A, B and C as depicted in Scheme 2 below.




With respect to the building blocks A, B and C, the encircled moieties, i.e. a in A, b in B and c1-c3 in C, shall represent their most basic skeletons appropriately and independently substituted as is detailed later on. The basic skeletons of a and b correspond to the ring systems depicted in Table 1 and Table 2.

Depending on the substitution pattern of skeletons b alternative binding modes are feasible. For skeletons b3 and b4 such incorporation via the exocyclic nitrogen atom is represented by the following two structures, which form part of the invention:




The encircled parts of the bridge subunits c1-c3 represent optionally substituted groups. Definitions of c1-c3 are exemplified in Table 3, each reading from the N-terminus to the C-terminus of the linker C. In the simplest case the linker C is constituted by one subunit c1, i.e. c1-1 to c1-6. For the embodiments consisting of two or three subunits all possible combinations of the subunits c1-c3 and the connectivities U, V and W are part of the invention.

And indices are defined as: q=0-4; r=2-4; s=1-4; t=0-2; and u=1-2.
Salts are especially the pharmaceutically acceptable salts of compounds of formula I.
Such salts are formed, for example, as acid addition salts, preferably with organic or inorganic acids, from compounds of type I with a basic nitrogen atom, especially the pharmaceutically acceptable salts. Suitable inorganic acids are, for example, halogen acids, such as hydrochloric acid, sulfuric acid, or phosphoric acid. Suitable organic acids are, for example, carboxylic, phosphonic, sulfonic or sulfamic acids, for example acetic acid, propionic acid, octanoic acid, decanoic acid, dodecanoic acid, glycolic acid, lactic acid, fumaric acid, succinic acid, adipic acid, pimelic acid, suberic acid, azelaic acid, malic acid, tartaric acid, citric acid, amino acids, such as glutamic acid or aspartic acid, maleic acid, hydroxymaleic acid, methylmaleic acid, cyclohexanecarboxylic acid, adamantanecarboxylic acid, benzoic acid, salicylic acid, 4-aminosalicylic acid, phthalic acid, phenylacetic acid, mandelic acid, cinnamic acid, methane- or ethane-sulfonic acid, 2-hydroxyethanesulfonic acid, ethane-1,2-disulfonic acid, benzenesulfonic acid, 2-naphthalenesulfonic acid, 1,5-naphthalene-disulfonic acid, 2-, 3- or 4-methylbenzenesulfonic acid, methylsulfuric acid, ethylsulfuric acid, dodecylsulfuric acid, N-cyclohexylsulfamic acid, N-methyl-, N-ethyl- or N-propyl-sulfamic acid, or other organic protonic acids, such as ascorbic acid.
As used in this description, the term “alkyl”, taken alone or in combinations (i.a. as part of another group, such as “arylalkyl”) designates saturated, straight-chain or branched hydrocarbon radicals having up to 24, preferably up to 12, carbon atoms. In accordance with a preferred embodiment of the present invention “alkyl” is “lower alkyl” which designated alkyl groups having up to 6 carbon atoms.
The term “alkenyl”, taken alone or in combinations, designates straight chain or branched hydrocarbon radicals having up to 24, preferably up to 12, carbon atoms and containing at least one or, depending on the chain length, up to four olefinic double bonds. Such alkenyl moieties can exist as E or Z configurations, both of which are part of the invention.
The term “alkynyl”, taken alone or in combinations, refers to an aliphatic hydrocarbon chain and includes, but is not limited to, straight and branched chains having 2 to 10 carbon atoms (unless explicitly specified otherwise) and containing at least one triple bond.
The term “cycloalkyl”, taken alone or in combinations, refers to a saturated alicyclic moiety having from three to ten carbon atoms.
The term “heterocycloalkyl”, taken alone or in combinations, describes a saturated or partially unsaturated heterocyclic moiety having from three to seven ring carbon atoms and one or more ring heteroatoms selected from nitrogen, oxygen and sulphur. This term includes, for example, azetidinyl, pyrrolidinyl, tetrahydrofuranyl, piperidinyl and the like.
The term “aryl”, taken alone or in combinations, designates aromatic carbocyclic hydrocarbon radicals containing one or two six-membered rings, such as phenyl or naphthyl, which may be substituted by up to three substituents such as Br, Cl, F, CF3, NO2, lower alkyl or lower alkenyl.
The term “heteroaryl”, taken alone or in combinations, designates aromatic heterocyclic radicals containing one or two five- and/or six-membered rings, at least one of them containing up to three heteroatoms selected from the group consisting of O, S and N and whereby the heteroaryl radicals or tautomeric forms thereof may be attached via any suitable atom. Said heteroaryl ring(s) are optionally substituted, e.g. as indicated above for “aryl”.
The term “arylalkyl”, as used herein, whether used alone or as part of another group, refers to the group —Ra-Rb, where Ra is an alkyl group as defined above, substituted by Rb, an aryl group, as defined above. Examples of arylalkyl moieties include, but are not limited to, benzyl, 1-phenylethyl, 2-phenylethyl, 3-phenylpropyl, 2-phenylpropyl and the like. Similarly, the term “lower arylalkyl”, refers to the above moiety —Ra-Rb but wherein Ra is a “lower alkyl” group.
The term “heteroarylalkyl”, whether used alone or as part of another group, refers to the group —Ra-Rc, where Ra is an alkyl group as defined above, substituted by Rc, a heteroaryl group, as defined above. Analogously the term “lower heteroarylalkyl”, refers to the above moiety —Ra-Rc but wherein Ra is a “lower alkyl” group.
The terms “alkoxy” and “aryloxy”, taken alone or in combinations, refer to the group —O—Ra, wherein Ra, is an alkyl group or an aryl group as defined above.
“Amino” designates primary (i.e. —NH2), secondary (i.e. —NRH) and tertiary (i.e. —NRR′) amines. Particular secondary and tertiary amines are alkylamines, dialkylamines, arylamines, diarylamines, arylalkylamines and diarylamines wherein the alkyl is as herein defined and optionally substituted.
The term “optionally substituted” is intended to mean that a group, such as but not limited to alkyl, alkenyl, alkynyl, cycloalkyl, aryl, heteroaryl, heterocycloalkyl, alkoxy and aryloxy may be substituted with one or more substituents independently selected from, e.g., halogen (F, Cl, Br, I), cyano (—CN), nitro (—NO2), —SRa, —S(O)Ra, —S(O)2Ra, —Ra, —C(O)Ra, —C(O)ORa, —C(O)NRbRc, —C(═NRa)NRRc, —ORa, —OC(O)Ra, —OC(O)ORa, —OC(O)NRbRc, —OS(O)Ra, —OS(O)2Ra, —OS(O)NRbRc, —OS(O)2NRbRc, —NRbRc, —NRaC(O)Rb, —NRaC(O)ORb, —NRaC(O)NRbRc, —NRa C(═NRd)NRbRc, —NRaS(O)Rb, —NRaS(O)2Rb, wherein Ra, Rb, Rc, and Rd are each independently, e.g., hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, aryl, heteroaryl, or heterocycloalkyl as described herein; or Rb and Rc may be taken together with the N atom to which they are attached forming heterocycloalkyl or heteroaryl. These groups in turn can be substituted with any described moiety, including, but not limited to, one or more moieties selected from the group consisting of halogen (fluoro, chloro, bromo, or iodo), hydroxyl, amino, alkylamino (e.g., monoalkylamino, dialkylamino, or trialkylamino), arylamino (e.g., monoarylamino, diarylamino, or triarylamino), hydroxy, carboxy, alkoxy, aryloxy, nitro, cyano, sulfonic acid, sulfate, phosphonic acid, phosphate, or phosphonate.
Said groups, especially but not limited to hydroxy, amino and carboxyl, may be either unprotected or protected, if necessary, as well-known to those skilled in the art. Examples of suitable protecting groups are as detailed in Peter G. M. Wuts, Theodora W. Greene, Greene's Protective Groups in Organic Synthesis, John Wiley and Sons, 4th Edition, 2006.
As used herein, all groups that can be substituted in one embodiment are indicated to be “optionally substituted,” unless otherwise specified.
As mentioned earlier herein, the term “lower” designates radicals and compounds having up to 6 carbon atoms. Thus, for example, the term “lower alkyl” designates saturated, straight-chain, or branched hydrocarbon radicals having up to 6 carbon atoms, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, s-butyl, isobutyl, t-butyl, and the like. Similarly, the term “lower cycloalkyl” designates saturated cyclic hydrocarbon radicals having up to 6 carbon atoms, such as cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and the like.
The present invention includes within its scope so-called “prodrugs” of the compounds of this invention. In general, such prodrugs will be functional derivatives of the compounds, which in vivo are readily convertible into the required compound. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in Hans Bundgaard, Design of Prodrugs, Elsevier, 1985; and in Valentino J. Stella et al., Prodrugs: Challenges and Rewards, Springer, 1st ed., 2007.
Some of the aforementioned substituents can occur several times within the same molecular entity, for example, but not limited to R14, R15, R16, R17, R18, R19, R28, R19, R30, R31, R32, R33, R39, R40, R41, R42, R43, R44, R45, R46, and R50. Each of such multiply occurring substituents shall be selected independently from the other radicals of the same type and within the scope of the definition of the respective group.
All possible stereoisomers, explicitly also including rotamers and atropisomers, of macrocycles of type I are part of this invention.
The general scope of the current invention is defined by groups of selected building blocks A, B and C and the appending substituents as outlined in this section.
Building blocks A1-A626 (Table 10) constitute a subset of possible building blocks based on the ring systems a1-a25 (Table 1). As structural characteristic, groups of type A carry one nucleophilic moiety XH (where X is O or S) and one carboxylic acid C(O)OH functionality. The underlying divalent radicals of type —X-a-CO— are an integral part of macrocyclic backbones of type I, into which they are incorporated by appropriate reactions of the XH and COOH groups of the respective starting materials with suitable reactants.
As mentioned earlier hereinabove, building blocks of type A act as templates and exert an important conformational constraint on products of type I. The structural effects of building blocks of type A depend largely on the relative orientation of the attachment vectors of —X— and —C(O)— and on the spatial distance between these groups. Molecular modeling revealed that the distances (typically between 2.5 and 7.5 Å) and vector arrangements for —X— and —C(O)— in A1-A626 (Table 10) vary considerably, thus strongly influencing the conformations of macrocycles of type I.

Divalent building blocks B1-B21 (Table 11, hereinbelow) constitute a subset of possible building blocks based on the ring systems b1-b11 (Table 2, above). They are based on optionally substituted cyclic secondary amines carrying a moiety of type —CHR3-LG, wherein LG is a suitable leaving group (e.g., but not limited to, —OH forming a suitable LG in situ during Mitsunobu reactions, or halogens like —Br or —I amenable to SN reactions) that can be replaced by the nucleophilic groups of building blocks A thus forming an ether (—O—) or a thioether (—S—) linkage between building blocks of type A and B. In most products of type I, the secondary amine nitrogen of building block B forms a tertiary amide linkage with the carboxyl group of building blocks of type C. In case a suitable exocyclic amine functionality is present, it can be, instead of the ring-nitrogen, involved in the formation of a secondary or preferably tertiary amide bond to C. Such an alternative binding mode is realized with, but not limited to B10.
By virtue of inducing peptidyl cis-trans isomerization or stabilizing cis amide bonds, building blocks of type B can function as conformational modulators in products of type I.

The divalent moiety C may consist of an ensemble of one to three subunits c1-c3, each derived from suitably protected and functionalized amine or amino acid derivatives. As a consequence the C moiety directly influences the ring size of the resulting macrocycle and can be regarded as spacer or linker. This linker ensemble C is joined to building block A via its N-terminus and to building block B via its C-terminus to form a macrocyclic ring of type I. According to its definition the connections within the linker ensemble, i.e. V or W, can be accomplished by amide bonds (—NR4—C(═O)—), an alkene[1,2]diyl (—CHR12═CHR13—), an alkane[1,2]diyl (—CHR12—CHR13—), or methylene-heteroatom moiety (—CHR3—Z—), an oxalyl unit (—C(═O)—C(═O)—) or a disulfide bridge (—S—S—). With respect to the macrocyclic backbone of I it follows that the linker C contributes at least one amide bonds.
Suitable linker C can be represented by, but are not limited to, the moieties shown in Table 12. For example C1 represents a linker moiety constituted of one to three α-amino acid derivatives connected along their main chains, while C7-C10 are equivalent to dipeptide moieties of β-amino acids. The simplest embodiments in which at least one connection between the subunits is realized by a non-amidic group are C2-C5. Finally C58-C101 shall depict situations in which a longer (>3 C-atoms) side chain connection of a suitable diamine or diacid is involved in an amide bond.

According to the preceding explanations, products of type I contain at least two amide bonds. As mentioned in the introduction, tertiary amide containing products generally show various ratios of cis and trans amide bond conformations in solution; this preference is in contrast to secondary amides that generally adopt trans conformations only. The occurrence of cis and/or trans conformations in macrocyclic natural products containing tertiary amides is well documented. In some cases a rapid equilibration between the cis and trans amide bonds, the so-called “peptidyl cis/trans isomerization”, is observed; whereas in other cases discrete cis and trans tertiary amide bonds are detected as two stable conformers in solution at room temperature.
All possible stereoisomers, including atropisomers, and distinct conformers or rotamers of macrocycles of type I are part of this invention.

In the aforementioned preferred structures the variable heteroatom Z and the connector U are defined as:

    
    
        Z: O; S(═O); or S(═O)2.
        U: —C(═O)—; —NR4—C(═O)—; —C(═O)—C(═O)—;
        or —C(—OR20)2—C(═O)—.
    
    


Defined as above are:

    
    
        Substituents that can be pairwise taken together and form optionally substituted cycloalkyl or heterocycloalkyl moieties.
        Structural elements that can form one of the groups of formulae H111-H118 (Table 9).
        Variable heteroatoms Q, T, X and Y.
        Indices q-u.
    
    


The above preferred structures include all possible stereoisomers, explicitly also including rotamers and atropisomers, of macrocycles of type I.
Particularly preferred among the building blocks of type A are A1(a1); A2(a1); A3(a1); A4(a1); A5(a1); A6(a1); A7(a1); A9(a1); A10(a1); A73(a2); A170(a4); A209(a7); A240(a10); A272(a10); A532(a18); A614(a24). For most of these building blocks, oxygen is the preferred nucleophilic moiety. However in the case of A170 it consists of a sulfur atom; and in the case of the three building blocks A5-A7, both oxygen and sulfur derivatives are part of the invention (Table 16).

Synthesis of the Building Blocks
Building blocks C used in the synthesis of the macrocyclic compounds of the invention are detailed to the level of fully-defined structures shown in Table 19, above and are easily available. Possible synthetic approaches to the modulator building blocks B and, especially, the production of the template building blocks A are described in some detail hereinbelow.
Synthesis of the Template Building Blocks A
General Transformations
Building blocks of type A are based on readily available substances carrying a carboxylic acid group and either a phenolic (Ar/Hetar-OH) or a thiophenolic moiety (Ar/Hetar-SH). The —COOH group may be attached to the same ring as the —OH/—SH group or to an annelated ring which in turn may be aromatic or partially unsaturated.
In general phenol derivatives are more abundantly described in the literature than the corresponding thiophenols. However, transformations of phenols into thiophenols are well established. Therefore the phenolic systems can be regarded as precursors towards their thio-analogs. Alternatively thiophenols might be derived from the corresponding aryl halides or diazonium salts.
Selected examples of general scope for the transformations Ar/Hetar-X→Ar/Hetar-SH(X═OH, F, Cl, Br, I, N2+) are introduced below:
T-I) A sequence of broad applicability is the transformation of a phenol into a thiocarbamate with N,N-dimethylthiocarbamoyl chloride, followed by Newman-Kwart rearrangement and subsequent hydrolysis (A. Gallardo-Godoy et al., J. Med. Chem. 2005, 48, 2407-2419; P. Beaulieu et al., Biorg. Med. Chem. Lett. 2006, 16, 4987-4993; H. Sugiyama et al., Chem. Pharm. Bull. 2007, 55, 613-624; S. Lin et al., Org. Prep. Proced. Int. 2000; 547-556).
T-II) The direct transformation of an —OH adjacent to a pyridinic nitrogen (equivalent to the pyridone tautomer) can be accomplished by heating with P2S5 (K. Hirai et al., Heterocycles 1994, 38, 277-280).
T-III) As an alternative to phenols, halogen-substituted (esp. with F or Cl) aromatic ring systems might serve as precursors. In case the halogen is in a position activated by an electron withdrawing group in ortho- or para-position the —SH moiety or a protected analog can be introduced under mild conditions by nucleophilic aromatic substitution reactions (SNAr) (G. J. Atwell et al., J. Med. Chem. 1994, 37, 371-380). Especially in the field of heterocyclic compounds, where the electron withdrawing effect is exerted by pyridine-like nitrogen atoms, this type of substitution is often utilized (S. McCombie et al., Heterocycles, 1993, 35, 93-97).
T-IV) Similarly, in Sandmeyer-type reactions a diazonium group (—N2+) is replaced (C. Mukherjee, E. Biehl, Heterocycles 2004, 63, 2309-2318).
T-V) In non-activated positions the substitution of halogen atoms (esp. Br or I) can be accomplished via the corresponding organolithium or Grignard reagents (J. L. Kice, A. G. Kutateladze, J. Org. Chem. 1993, 58, 917-923; P. C. Kearney et al., J. Am. Chem. Soc. 1993, 115, 9907-9919; K.-Y. Jen, M. P. Cava, Tetrahedron Lett. 1982, 23, 2001-2004). Alternatively, transition metal-catalyzed transformations are feasible for this type of reaction, e.g. Cu-catalyzed substitution with benzothioic S-acid (N. Sawada et al., Tetrahedron Lett. 2006, 47, 6595-6597), or Pd-catalyzed substitution with KS-Si(i-Pr)3 followed by desilylation of the thus introduced —SSi(i-Pr)3 group (A. M. Rane et al., Tetrahedron Lett. 1994, 35, 3225-3226).
The hydroxyl group attached to the aromatic ring (Ar—OH or Hetar-OH) in turn, if not part of a commercially available substance, can be introduced by various methods:
H-I) Analogously to T-III) the hydroxy group or a surrogate can be introduced by an SNAr reaction of halogen atoms, esp. Cl or F, ortho or para to an electron withdrawing substituent (W. Cantrell, Tetrahedron Lett. 2006, 47, 4249-4251) or to a pyridinic nitrogen atom (S. D. Taylor et al., J. Org. Chem. 2006, 71, 9420-9430).
H-II) Sandmeyer-type hydroxylations of aromatic amines via intermediate diazonium salts (P. Madsen et al., J. Med. Chem. 2002, 45, 5755-5775).
H-III) The substitution of halogen atoms (esp. Br and I), not activated for an SNAr, can be achieved by transition metal-catalyzed C—O-couplings; predominant are Pd-catalysts (K. W. Anderson et al., J. Am. Chem. Soc. 2006, 128, 10694-10695; B. J. Gallon et al., Angew. Chem., Int. Ed. 2007, 46, 7251-7254), but also others, like Cu-catalysts (J. E. Ellis, S. R. Lenger, Synth. Commun. 1998, 28, 1517-1524), find application.
H-IV) Of broad scope is also a two-step process which first transforms halogen atoms (Cl, Br and I) into a boronate and then oxidatively cleaves the carbon-boron bond to the phenol (J. R. Vyvyan et al., J. Org. Chem. 2004, 69, 2461-2468).
The carboxylic acid groups of template building blocks A, if not already present in a commercial available building block, can be introduced by standard procedures:
C-I) The oxidation of functional groups like hydroxymethyl (—CH2—OH) or aldehyde (—C(═O)H) can be achieved under mild conditions (G. V. M. Sharma et al., Synth. Commun. 2000, 30, 397-406; C. Wiles et al., Tetrahedron Lett. 2006, 47, 5261-5264). Also methyl groups on benzene rings can be oxidized; however, as harsh reaction conditions are usually required, its applicability is limited. In contrast, the relative acidic methyl groups ortho or para to a pyridine nitrogen can be oxidized under milder conditions; making this the method of choice for many pyridine ring analogs (T. R. Kelly, F. Lang, J. Org. Chem. 1996, 61, 4623-4633).
C-II) Halogen atoms can easily be replaced by a carboxyl group or surrogates thereof, e.g. by halogen metal exchange and subsequent carboxylation of the intermediate Grignard or organolithium species (C. G. Screttas, B. R. Steele, J. Org. Chem. 1989, 54, 1013-1017), or by utilizing Mander's reagent (methyl cyanoformate) (A. Lepretre et al., Tetrahedron 2000, 56, 265-274).
C-III) In the case that acidified ring positions are to be carboxylated, a viable method is deprotonation with a strong base (usually tert-butyl lithium) followed by carboxylation of the intermediate organolithium species in analogy to C-II).
C-IV) Hydrolysis of ester, amide or nitrile groups. The CN group in turn can easily be introduced by treating organic halides with CuCN (Rosenmund-von Braun reaction: C. F. Koelsch, A. G. Whitney, J. Org. Chem., 1941, 6, 795-803).
Applied to commercially available starting materials these general transformations offer a tool box for accessing templates A. Further literature example are cited within the category of each embodiment below.
A1-A59 Phenyl Derivatives
A plethora of hydroxy benzoic acids with diverse substitution patterns are commercially available and can be directly incorporated as template A into the macrocyclic backbone. In several other cases the presence of an optional substituent provides a suitable functionality that can be further extended into more complex high variation substituents by standard methods of organic synthesis and parallel/combinatorial chemistry.
Even not so common tetrasubstituted hydroxy benzoic acids (A53-A59) can be built up by procedures in accordance with the general methods mentioned above, for example by carboxylation of pentasubstituted phenol derivatives (K. Sung, R. J. Lagow, J. Mater. Chem. 1996, 6, 917-918; E. Marzi, M. Schlosser, Tetrahedron 2005, 61, 3393-3402; K. C. Nicolaou et al., Angew. Chem., Int. Ed. 1999, 38, 3334-3339). Alternative approaches to tetrasubstituted hydroxy benzoic acids involve, for example, the oxidation of benzaldehydes followed by the introduction of substituents into remaining free positions, also feasible to build up polysubstituted benzoic acids from less substituted ones (K. C. Nicolaou et al., Chem. Eur. J. 2000, 6, 3095-3115).

As in the case of the above class of compounds also for pyridine derivatives a very large number of substances are commercially available which can be incorporated into the macrocycle directly, or can easily be transformed into suitable hydroxyl pyridine carboxylic acids by the general methods mentioned above: selected literature examples can be cited for transformations of type C-III (M. Shimano et al. Tetrahedron Lett. 1998, 39; 4363-4366; ibid., Tetrahedron 1998, 54, 12745-12774); for H-II (L. Carpino et al., J. Org. Chem. 2004, 69; 54-61); and for C-I (T. R. Kelly, F. Lang, Tetrahedron Lett. 1995, 36, 5319-5322), or for C-IV (J. L. LaMattina, R. L. Taylor, J. Org. Chem. 1981, 46, 4179-4182).
A144-A165 Pyridazine Derivatives
In analogy to general transformations which are readily available, suitably substituted methylpyridazines can be oxidized to the corresponding 3- or 4-carboxylic acids with dichromate (M. Morishita et al., Chem. Pharm. Bull. 1994, 42, 371-372; M. Winn et al., J. Med. Chem. 1993, 36, 2676-2688). Of similarly broad scope is the hydrolysis of the corresponding nitriles under chemical conditions (hydroxide; G. Heinisch, D. Lassnigg, Arch. Pharm. (Weinheim, Ger.) 1987, 320, 1222-1226) or under enzymatic conditions (nitrilase from Rhodococcus sp.; N. Klempier et al., Tetrahedron Lett. 1991, 32, 341-344). One possibility to construct the heterocyclic pyridazine core from non-cyclic precursors starts with β-ketoesters which can be subjected to a Staudinger reaction followed by a aza-Wittig-cyclization of the intermediate azides (S. V. Galiullina et al., Russ. J. Org. Chem. 2007, 43, 607-614; M. Guillaume et al., Synthesis 1995, 8, 920-922) or directly cyclocondensed with monohydrazone (E. E. Schweizer, K.-J. Lee, J. Org. Chem. 1982, 47, 2768-2773).
A166-A189 Pyrimidine Derivatives
Similarly as with the pyridine derivatives, a large number of suitable building blocks are commercially available and can be directly incorporated into the macrocycle, or they can easily be transformed into the target compounds by the standard procedures mentioned above, including selected examples for transformations of type C-I (Y. Honma et al., Chem. Pharm. Bull. 1982, 30, 4314-4324); and C-IV (I. V. Oleinik, O. A. Zagulyaeva, Chem. Heterocycl. Compd. 1993, 29, 427-431). In addition, the pyrimidine core can easily be constructed by cyclocondensation of oxalylic compounds with malonamidine derivative (G. A. Howard et al., J. Chem. Soc. 1944, 476-477) or of malonates with amidine derivatives (M. Otsuka et al., Chem. Pharm. Bull. 1985, 33, 515-519).
A190-A200 Pyrazine Derivatives
Pyrazine carboxylic acids are easily obtained by cyclocondensation of α,β-diaminopropionic acid with α,β-dicarbonyl derivatives (J. Bostroem et al., Bioorg. Med. Chem. 2007, 15, 4077-4084). Standard protocol examples are for C-I (J. R. Young et al., Bioorg. Med. Chem. Lett. 2000, 10, 1723-1728); for C-111 (N. Ple et al., Tetrahedron 1998, 54, 9701-9710); and for H-II (A. P. Krapcho et al., J. Heterocycl. Chem. 1997, 34, 27-32). Highly chemosoelective oxidations of type C-I can be achived by biotransformations with Pseudomonas putida (A. Kiener, Ang. Chem. 1992, 104, 748-749).
A201-A206 Triazine Derivatives
A possible route to suitably substituted precursors of difunctional triazines is the cyclocondensation of amidrazones with α,β-diketones or α,β-diketoesters (M. Sagi et al., Heterocycles 1990, 30, 1009-1021). Also α,γ-diketoesters are described as suitable starting materials, in this case, however, a multi step reaction sequence being required that proceeds via intermediate 4-nitrosopyrazoles (R. Fusco, S. Rossi, Tetrahedron 1958, 3, 209-224).
A207-A228 Furan, Thiophene and Pyrrole Derivatives
The furans A207 and A208 can be synthesized from suitably substituted 2-formyl- or 2-acetyl-3-oxo-butanoates by bromination followed by cyclization (A. Becker, Helv. Chim. Acta 1949, 32, 1114-1122; R. Richter, Helv. Chim. Acta 1949, 32, 1123-1136). The thiophenes A207 and A208 can be prepared from (substituted) 3-methoxycarbonyl-tetrahydrothiophene-4-one by oxidation (M. R. Banks et al., J. Chem. Res. (M) 1984, 369-389) or by condensation with aldehydes followed by isomerization (R. Jaunin, Helv. Chim. Acta 1980, 63, 1542-1553). The pyrroles A207 and A208 (X═O) can be obtained from N-protected, suitably substituted 3-amino-acrylates by reaction with (substituted) 2-chloroacetyl chlorides followed by base-induced cyclization (E. Benary, R. Konrad, Chem. Ber. 1923, 56, 44-52). The thioanalogues (X═S) can be synthesized from 3-methoxycarbonyl-furan by dibromination/methanolysis, subsequent reaction with 3-mercapto-propionate and amines, followed by acid-induced cyclization and S-deprotection (F. Eiden, U. Grusdt, Arch. Pharm. 1989, 322, 807-810).
The furans A209 and A210 (X═O) are accessible from (substituted) acetyl(methoxycarbonyl)methylene]-triphenylphosphorane by reaction with aldehydes followed by ozonolysis and acid-induced isomerization (H.

Wasserman et al., Tetrahedron Lett. 1989, 30, 1721-1724) or by reaction of suitably substituted 3-oxo-propanoates with glycine esters (A. Treibs, A. Ohorodnik, Liebigs Ann. Chem. 1958, 611, 139-149). The thioanalogues (X═S) can be synthesized from (substituted) pyrrolidine-2-carboxylates by subsequent reaction with bistosylsulfur diimide and trimethylphosphite followed by demethylation (J. Häusler, Monatsh. Chem. 1986, 117, 269-274).
The furans of type A211 and A212 can be synthesized from diazomalonates and suitably substituted alkynes in a two-step-procedure catalyzed by rhodium(II)-acetate (P. Müller, C. Gränicher, Helv. Chim. Acta 1993, 76, 521-534). The thioanalogues (X═S) can be obtained from suitably substituted oxazoles by deprotonation and reaction with dimethyl disulfide, then bromination, lithiation and carboxylation followed by demethylation (S. M. Nolan, T. Cohen, J. Org. Chem. 1981, 46, 2473-2476). The thiophenes A211 and A212 are accessible from (substituted) thiophenes by 5-alkylation and/or 3-carboxylation by deprotonation or lithiation (J. Sicé, J. Am. Chem. Soc. 1953, 75, 3697-3700). The thioanalogues (X═S) can be obtained from (substituted) 2-trimethylsilyloxy-cyclopropanecarboxylates by reaction with carbon disulfide (C. Brückner, H.-U. Reissig, Liebigs Ann. Chem. 1988, 465-470).
The pyrroles A211 and A212 can be prepared from suitably substituted 2-chloroethylidene-malonates by substitution with sodium azide followed by cyclization in the presence of triphenylphosphine (F.-P. Montforts et al., Liebigs Ann. Chem. 1990, 1037-1043). The thioanalogues (X═S) can be obtained from suitably substituted 2-oxoethyl-malonates by reaction with isothiocyanates followed by acid-induced cyclization and decarboxylation (J. Fuentes et al., Tetrahedron: Asymm. 1998, 9, 2517-2532).
Furans of type A213 and A214 are accessible either by 5-lithiation/carboxylation of (substituted) O-protected 2-hydroxy-furans or by 5-bromination of furan-2-carboxylates followed by substitution with methylate and demethylation (D.

Datta et al., Tetrahedron 1989, 45, 7631-7641). The thiophenes A213 and A214 can be prepared analogously as for the compounds A211 and A212 (J. Sicé, J. Am. Chem. Soc. 1953, 75, 3697-3700). The thioanalogues of thiophenes A213 and A214 (X═S) can be synthesized from suitably substituted 2-chloro-thiophenes by 5-carboxylation and subsequent substitution with sodium hydrogensulfide (K. Clarke et al., J. Chem. Soc., Perkin Trans. 11980, 1029-1037). The pyrrols A213 and A214 can be obtained from suitably substituted, N-protected glutamate, which is transformed into the didehydro derivative and cyclized in the presence of LiCuMe2 (M. M. Paz., F. J. Sardina, J. Org. Chem. 1993, 58, 6990-6995). The thiophenes A215 and A216 (X═S) can be synthesized from (substituted) 3-bromo-thiophenes by a sequence of 3-lithiation/sulfanylation, 2-bromination, 4-lithiation/carboxylation, 2-debromination and 3-demethylation (E. C. Taylor, D. E. Vogel, J. Org. Chem. 1985, 50, 1002-1004). The pyrroles A215 and A216 can be prepared from aminooxoacetate and oxalyl chloride, alcoholysis of the isocyanate, reaction with (3-bromoacetonyl)triphenylphosphonium bromide and N-deprotection (J. P. Bazureau et al., Tetrahedron Lett. 1988, 29, 1921-1922), or from (substituted) N-Pfp-protected 3-oxo-prolinates by subsequent reaction with base and acid (F.-A. Marcotte, W. D. Lubell, Org. Lett. 2002, 4, 2601-2603). The thioanalogues (X═S) can be obtained from suitably substituted pyrrole-2-carboxylates by subsequent reaction with dicyanodisulfane and zinc/acetic acid (A. Berlin et al., J. Chem. Soc, Perkin Trans. 2 1990, 5, 699-704).
The furans A217 and A218 may be obtained from (substituted) acetylene carboxylates by reaction with suitably substituted ethoxyvinylidene-tetracarbonyl-ferrocene complexes followed by O-deprotection (Atiq-ur-Rehman et al., J. Am. Chem. Soc. 1993, 115, 9848-9849). The thioanalogues (X═S) can be synthesized from suitably substituted furan-3-carboxylates by subsequent 5-bromination, reaction with dimethyl disulfide and S-deprotection (G. Majetich et al., Tetrahedron Lett. 1994, 35, 4887-4890). The thiophenes A217 and A218 should be accessible from (substituted) formylsuccinates by cyclization in the presence of methanol, hydrogen chloride and hydrogen sulfide, followed by demethylation (S. Mitra et al., J. Chem. Soc. 1939, 1116-1117); or from (substituted) 2,4-dibromothiophene by subsequent reaction with methanol, butyllithium and carbon dioxide followed by demethylation (D. Spinelli et al., J. Chem. Res. (M) 1993, 8, 1873-1890). The pyrroles A217 and A218 (keto-tautomer) can be obtained from suitably substituted aminomethylene succinates by base-induced cyclization (C.

The oxazoles of type A229 can be obtained by reaction of acetyl isocyanates and diazoacetate followed by cyclization (O. Tsuge et al., Tetrahedron 1973, 29, 1983-1990), whereas the thiazoles A229 can be synthesized from bromomalonates and thioamides (F. A. J. Kerdesky et al., J. Med. Chem. 1991, 34, 2158-2165). The imidazoles A229 are accessible by reaction of aminomalonate with substituted acetimidates (M. S. Poonian, E. F. Nowoswiat, J. Org. Chem. 1980, 45, 203-208).
The oxazoles and thiazoles of type A230 are accessible by cyclizing monoethyl acetamidomalonate in the presence of trifluoroacetic anhydride (to the oxazoles; J. Morgan et al., J. Chem. Soc., Perkin Trans. 1 1997, 5, 613-620), or in the presence of phosphorus pentasulfide (to the thiazoles; A. G. Long, A. Tulley, J. Chem. Soc. 1964, 1190-1192). The thiazoles A230 (with X═S) can be synthesized either from N-thioacetyl-glycine by PCl3-mediated cyclization followed by subsequent reaction with the Vilsmeyer reagent and hydrosulfide and oxidation of the intermediate aldehyde (to give 2-substituted 5-mercapto-thiazoles; I. Y. Kvitko et al., Chem. Heterocycl. Comp. 1980, 16, 28-31) or from (substituted) 3-bromo-2-oxo-propionic acid by reaction with thiourea, 2-deamination via diazotation, 5-bromination, substitution and deprotection (to give 2-unsubstituted 5-mercapto-thiazoles; B.

The imidazoles A230 (X═O) can be obtained from aminomalonate by reaction with trimethylorthoformiate followed by cyclization in the presence of ammonia or amines (R. S. Hosmane, B. B. Lim, Tetrahedron Lett. 1985, 26, 1915-1918) or, for (X═S) by subsequent reaction of 2-amino-2-cyano-acetate with (substituted) trimethylorthoformiate and hydrogen sulfide A. K. Sen, A. K. Mukhopadhyay, Indian J. Chem. B. 1981, 20, 275-278).
The oxazoles A231 (X═S) should be obtainable starting from hydroxyacetaldehyde dimer and potassium thiocyanate followed by S-methylation, lithiation/acylation with chloroformiate and demethylation (C. M. Shafer, T. F. Molinski, J. Org. Chem. 1998, 63, 551-555). The corresponding thiazoles A231 (X═S) may be synthesized from suitably substituted beta-ketoesters by subsequent reaction with [hydroxy(tosyloxy)iodo]benzene and ammonium dithiocarbamate (P.-F. Zhang, Z.-C. Chen, Synth. Comm. 2001, 31, 415-420). The imidazoles A231 (X═S) can be prepared from N-protected glycine by subsequent reaction with formic acid, methyl formiate and potassium thiocyanate (G. van Lommen et al., Bioorg. Med. Chem. Lett. 2005, 15, 497-500), or by C-alkylation of N-protected glycine with suitably substituted chloroacetates followed by reaction with potassium thiocyanate (J. Singh et al., Tetrahedron Lett. 1993, 34, 211-214). Oxazoles of type A232 can be prepared from suitably substituted diazoacetates by rhodium-catalyzed reaction with cyanoformiate (G. Shi et al., J. Fluorine Chem. 1991, 52, 149-157). Oxazoles of type A233 can be obtained by heating suitably substituted acetylene carboxylates with diazoacetate followed by demethylation (R. Huisgen, H. Blaschke, Chem. Ber. 1965, 98, 2985-2997). The S-analogues of oxazoles A233 (X═S) are accessible from N-(bismethylthio)glycine esters by reaction with DMF-acetals followed by acid-induced cyclization and demethylation (R. Gompper, U. Heinemann, Angew. Chem. 1981, 93, 297-298). The thiazoles A233 (X═O) can be prepared from suitably substituted cysteine ethyl ester by reaction with diphosgene followed by bromination/elimination (G.

The oxazoles A234 (X═O) can be prepared from suitably substituted hydroxyacetonitriles and oxalyl chloride followed by methanolysis of the intermediate and demethylation (K. van Aken, G. Hoornaert, J. Chem. Soc., Chem. Comm. 1992, 12, 895-896). The thiazoles A234 (X═O) are accessible from suitably substituted 2-mercaptoacetate and cyanoformiate (G. Satzinger, Liebigs Ann. Chem. 1978, 473-511). The corresponding thioanalogues (X═S) can be prepared from (substituted) S-methyl 3-oxopropanedithioates and glycine esters followed by cyclization induced by thionyl chloride and demethylation (A. Rahman et al., Synthesis 1984, 250-252).
A235-A239 Isoxazole, Isothiazole and Pyrazole Derivatives
Isoxazoles A235 can be synthesized from (2-methoxymethylene)-malonate substituted in 2-position by reaction with hydroxylamine followed by aqueous HCl (K. Bowden et al., J. Chem. Soc. C 1968, 172-185). The corresponding pyrazoles A235 can be prepared similarly but with hydrazine instead of hydroxylamine (T. M. Willson et al., Bioorg. Med. Chem. Lett. 1996, 6, 1047-1050).
The isothiazoles A236 can be obtained from suitably substituted O-toluenesulfonyloxyiminoacetates by reaction with thioglycolates (B. Rezessy et al., Tetrahedron Lett. 1992, 33, 6523-6526). The corresponding pyrazoles A236 can be prepared either from suitably substituted 2-oxopropionates by reaction with ethyl hydrazinoacetate followed by methoxide-mediated cyclization (R. N. Comber et al., Carbohyd. Res. 1992, 216, 441-452) or from substituted 3-oxopropionates by 2-diazotation followed by cyclization in the presence of sodium hydride (F. J. L. Herrera, C. U. Baelo, Carbohyd. Res. 1985, 143, 161-174). The isoxazoles A237 are accessible by reaction of 4-chloro-3-oxo-butanoates substituted in 4-position with isopentylnitrite (G. Hesse, G. Krehbiel, Chem. Ber. 1955, 88, 130-133). The pyrazoles A237 can be obtained from suitably substituted malonates by reaction with diazoacetate (A. Bertho, H. Nüssel, Liebigs Ann. Chem. 1927, 457, 278-307). The pyrazoles of type A238 (keto-isomers) can be synthesized from suitably substituted ketosuccinic acids by reaction with hydrazines in the presence of acetic acid (K. J. Duffy et al., J. Med. Chem. 2001, 44, 3730-3745).
Isoxazoles of type A239 can be obtained from 3-substituted 2-bromomaleic acids by esterification followed by reaction with hydroxyurea (C. Bennouna et al., Bull. Soc. Chim. Fr. 1980, 2, 478-480). The isothiazoles A239 can be prepared from 3-substituted 2-aminofurmaramides by subsequent reaction with hydrogen sulfide and bromine followed by hydrolysis of the formed amides (J. Lykkeberg, P. Krogsgaard-Larsen, Acta Chem. Scand. B 1976, 30, 781-785). The corresponding pyrazoles are accessible from (substituted) maleates by reaction with hydrazines followed by oxidation to give the pyrazole ring (G. P. Lahm et al., Bioorg. Med. Chem. Lett. 2007, 17, 6274-6279).
A240-A357 Benzofurane, Benzothiophene and Indole Derivatives
The benzothiophenes A240 can be prepared in a multistep sequence starting from suitably substituted 2-hydroxy-benzaldehydes, which are transformed into the 3-isopropoxy-2,3-dihydrobenzothiophen-2-ones and then further on functionalized in 2-position and carboxylated in 3-position (A. V. Kalinin et al., J. Org. Chem. 2003, 68, 5992-5999).
A possible route to benzofuranes of type A241-A243 involves condensation of suitably substituted cyclohexane-1,3-diones and 3-bromo-2-oxo-propionic acid followed by Pd-catalyzed dehydrogenation (G. Kneen, P. J. Maddocks, Synth. Comm. 1986, 16, 1635-1640). The indoles A244-A247 can be obtained from suitably substituted 2-bromo-3-nitro-benzoates by a Stille coupling to the corresponding 1-ethoxy-styrene followed by a Pd-catalyzed reductive cyclization in the presence of CO and subsequent deprotection of the alcohol and acid (R. W. Clawson et al., Tetrahedron 2006, 62, 10829-10834).
The benzofuranes of type A248-A251 can be synthesized from suitably substituted 2,6-dihydroxy-benzoates by reaction with 2-chloroketones (F. H. Curd, A. Robertson, J. Chem. Soc. 1933, 714-720) or with chloroacetonitrile in the presence of Lewis acids and HCl followed by acetylation and reductive deoxygenation in 3-position (W. Gruber, K. Horvath, Mh. Chem. 1950, 81, 828-836). The corresponding indoles A250 and A251 should accessible from 6-hydroxy-3-methyl-2-nitro-benzoic acid, which is reacted with dimethylformamide followed by hydrogenation of the nitro group, cyclization, diazotation of the amine and hydroxylation (H. D. Hollis Showalter et al., J. Org. Chem. 1996, 61, 1155-1158). The benzothiophenes A250 and A251 could be obtained from suitably substituted 2-(thiophen-3-yl-)acetaldehydes by reaction with propargyl alcohol followed by iodo-cyclization, oxidation of the alcohol to the acid and transformation of the 6-iodo-compound into the alcohol (J. P. Waldo et al., J. Org. Chem. 2008, 73, 6679-6685).
The benzothiophenes of type A252-A255 are accessible from suitably substituted methyl 3-methyl-thiophene-2-carboxylate, which is first transformed into the 3-toluenesulfinylmethyl compound and then further reacted with suitably substituted acrylates in the presence of base to give the methyl esters of A252-A255 (J. W. Terpstra, A. M. van Leusen, J. Org. Chem. 1986, 51, 230-238). Indoles A252-A255 can be synthesized from methyl 2-methoxy-4-methyl-benzoates, which are subsequently brominated in 5-position, nitrated in 3-position, then reacted with dimethylformamide and reduced with Ra/Ni and hydrazine, which triggers a cyclization to the 7-methoxy-6-methoxycarbonyl-indoles. These intermediates can then be deprotected to the indoles A252-A255 (P. L. Beaulieu et al., Bioorg. Med. Chem. Lett. 2006, 16, 4987-4993).
Possible precursors for benzofuranes A256-A259 and A264-A267 are suitably substituted 2,4-dihydroxy-benzoates which are subjected to alkylation in 4-position with bromoacetaldehyde diethyl acetal followed by cyclization mediated by Amberlyst A15 (M. Dixit et al., Synlett 2006, 10, 1497-1502). Indoles of type A256-A259 (TMS-protected in 4-position, if there is no other substituent) and A264-A267 can be obtained from suitably substituted 5-hydroxy-indoles by formation of the diethyl carbamate followed by anionic Fries rearrangement to the diethyl amide, which is subsequently hydrolyzed with aqueous sodium hydroxide or perchloric acid (E. J. Griffen et al., J. Org. Chem. 1995, 60, 1484-1485). The benzothiophenes of type A260 and A263 should accessible from 4,6-dibromo-benzene-1,3-carbaldehyde (substituted in 2- or 5-position) by subsequent substitution of the bromides with methoxide and with 2-mercaptoacetate followed by cyclization, decarboxylation, demethylation and oxidation of the aldehyde to the acid (A. E. Jakobs et al., Tetrahedron 1994, 50, 9315-9324).
Benzofuranes of type A268-A271 can be synthesized from the corresponding 4-hydroxy-benzofuranes by carboxylation with carbon dioxide in the presence of methoxide (T. Reichstein, R. Hirt, Helv. Chim. Acta 1933, 16, 121-129) or from suitably substituted 5-carbomethoxy-6-hydroxy-salicylaldehydes by reaction with bromoacetates followed by saponification and cyclization in the presence of acetic anhydride (R. T. Foster, A. Robertson, J. Chem. Soc. 1948, 115-116). The preparation of the corresponding benzothiophenes A268-A271 should be possible from suitably substituted 4-oxo-tetrahydrobenzothiophene by acylation with dimethyl carbonate followed by aromatization with DDQ (P. P. Yadav et al., Bioorg. Med. Chem. 2005, 13, 1497-1505). The indoles A268-A271 can be prepared similarly from the 4-oxo-tetrahydroindoles, or alternatively from suitably substituted N-protected 4-amino-salicylic acid via Claisen rearrangement of the O-allyl ether followed by cleavage of the double bond and cyclization (T. Kakigami et al., Chem. Pharm. Bull. 1988, 46, 42-52). Benzofuranes of type A273-A275 can be obtained from 4-O-protected 4-hydroxy-salicylaldehydes by reaction with ethyl diazoacetate in the presence of tetrafluoroboric acid followed by dehydration and deprotection (M. E. Dudley et al., Synthesis 2006, 1711-1714). The benzothiophenes A272-A275 are accessible from 5-bromo-benzothiophene (which, in turn, can be prepared from suitably substituted 4-bromo-thiophenols and bromoacetaldehyde diethyl acetal) by Friedel-Crafts acylation, conversion of the methyl ketone into the carboxylate, substitution of the bromide with methoxide and demethylation (S. Mitsumori et al., J. Med. Chem. 2003, 46, 2446-2455). The synthesis of corresponding indoles A272-A275 should be possible by the reaction of suitably substituted para-benzoquinones with substituted 2-aminoacrylates in a Nenitzescu reaction (E. A. Steck et al., J. Org. Chem. 1959, 24, 1750-1752) Benzofuranes of type A276-A279 can be obtained from the 3-acetyl-4-hydroxy-benzoates by bromination of the methyl ketone followed by base-induced cyclization to the keto-tautomer of A276-A279 (G. Doria et al., Farmaco 1980, 35, 674-680). The synthesis of 2-substituted benzofuranes A278 can be achieved by alkylation or acylation. The corresponding benzothiophenes A276-A279 may be prepared from suitably substituted 4-fluorobenzoates and thioglycolate by AlCl3-induced intramolecular Fridel-Crafts acylation of the intermediate 4-alkoxycarbonyl-phenylsulfanyl acetates (D. L. Gernert et al., Bioorg. Med. Chem. Lett. 2004, 14, 2759-2764).
The benzofuranes and benzothiophenes of type A284-A287 can be synthesized from suitably substituted 3-furaldehydes or 3-formyl-thiophenes by condensation with diethyl succinate followed by cyclization in the presence of acetic anhydride and then base (D. Simoni et al., J. Med. Chem. 2006, 49, 3143-3152). The indoles of type A284 and A287 are accessible from 3-methoxy-4-amino-benzoates by subsequent 5-iodination, Sonogashira coupling with TMS-acetylene and CuI-mediated cyclization followed by demethylation (J. Ezquerra et al., J. Org. Chem. 1996, 61, 5804-5812). Benzofuranes and benzothiophenes of type A288-A291 can be obtained from suitably substituted 2-furaldehydes similarly as described for A284-A287 (D. Simoni et al., J. Med. Chem. 2006, 49, 3143-3152). The indoles A288-A291 can be synthesized similarly from pyrrole-2-carbaldehydes and diethyl succinate followed by base-induced cyclization (C. Fuganti, S. Serra, J. Chem. Res. (M) 1998, 10, 2769-2782).
The indoles of type A292-A295 can be prepared from N-protected ethyl furo[3,2-b]pyrrole-5-carboxylates by decarboxylation with copper chromite in quinoline followed by Diels-Alder reaction with ethyl propiolate and subsequent deprotection (A. Krutosikova, M. Hanes, Collect. Czech. Chem. Comm. 1992, 57, 1487-1494).
Benzofuranes of type A296-A299 can be obtained from suitably substituted (p-acetoxyphenoxy)acetyl chlorides by reaction with cyanide followed by cyclization with 1,3-dihydroxy-benzene mediated by zinc(II)-chloride and hydrogen chloride (L. Crombie et al., J. Chem. Soc., Perkin Trans. 1 1987, 2783-2786). The corresponding benzothiophenes A296-A299 can be synthesized from suitably substituted 3-bromothiophenols similarly to the synthesis of A272-A275 (S. Mitsumori et al., J. Med. Chem. 2003, 46, 2446-2455). The access of the indoles A296-A299 can be achieved either from O-protected 6-hydroxyindoles by acylation in 3-position with trichloroacetyl chloride and methanolysis followed by deprotection (M. Fedouloff et al., Bioorg. Med. Chem. 2001, 9, 2119-2128) or by acylation of suitably substituted indoles in 3-position followed by 6-hydroxylation via a Friedel-Crafts acylation/Baeyer-Villiger oxidation sequence (S, Nakatsuka et al., Heterocycles 1987, 26, 1471-1474).
The benzofuranes A300-A303 can be obtained from suitably substituted 3-acetyl-furanes by transformation into the silylenol ether followed by Diels-Alder reaction, elimination and dehydrogenation (A. Benitez et al., J. Org. Chem. 1996, 61, 1487-1492).
The benzofuranes A304-A307 can be synthesized either from substituted 2-allyl-3-allyloxy-4-methoxy-benzaldehydes by isomerization/metathesis followed by oxidation of the aldehyde and demethylation (W. A. L. van Otterlo et al., Tetrahedron 2005, 61, 7746-7755) or from substituted 2-hydroxy-3-methoxy-6-bromo-benzaldehydes by reduction of the alcohol, formation of the phosphonium salt and cyclization in the presence of an acid chloride followed by lithiation/carboxylation and demethylation (K. Hagihara et al., Bioorg. Med. Chem. Lett. 2007, 17, 1616-1621). The corresponding benzothiophenes A304-A307 are accessible from suitably substituted methyl thiophene-2-carboxylates by transformation into the 1-(2′-thienyl)-1,4-dioxobutanes followed by BF3-mediated cyclization, 4-carbonylation by Vilsmeyer-Haack reaction, oxidation of the aldehyde and demethylation (S. S. Samanta et al., J. Chem. Soc., Perkin Trans. 1 1997, 3673-3678).
The indoles A304-A307 can be obtained either by Diels-Alder reaction of the silylenolate of N-protected 2-acetylpyrrole with propiolate followed by air oxidation (M. Ohno et al., Heterocycles 1991, 32, 1199-1202) or from suitably substituted 4-benzyloxy-2-methyl-3-nitro-benzoates (prepared from the 3-methylphenols in a multistep sequence) by subsequent reaction with dimethylformamide and zinc/acetic acid followed by deprotection (M. Tanaka et al., Eur. J. Med. Chem. 1996, 31, 187-198).
A358-A372 Pyrrolo[2,3-b]Pyridine Derivatives
The pyrrolopyridines A365 and A366 can be synthesized from 7-azaindole, which is first transformed into N-protected 4-chloro-7-azaindole via the pyridyl-N-oxide (X. Wang et al., J. Org. Chem. 2006, 71, 4021-4023), followed by 5-lithiation and carboxylation, hydrolysis of the chloride and of the ester and N-deprotection (A. L'Heureux et al., Tetrahedron Lett. 2004, 45, 2317-2320). The pyrrolopyridines of type A367 and A368 can be obtained from suitably substituted 4-chloro-3-formyl-pyridines by reaction with azidoacetate followed by a Hemetsberger-Knittel reaction (P. J. Roy et al., Synthesis 2005, 2751-2757). The pyrrolopyridines of type A369 and A370 may be accessible from the corresponding substituted 5-chloro-pyrrolopyridine by formylation in a Duff reaction, oxidation to the acid and hydrolysis of the chloride (R. H. Bahekar et al., Bioorg. Med. Chem. 2007, 15, 6782-6795) The synthesis of pyrrolopyridines A371 and A372 may be possible from 4-chloro-7-azaindole by pyridyl-N-oxidation and -methylation followed by substitution with cyanide and hydrolysis of the nitrile and chloride (T. Storz et al., Synthesis 2008, 201-214).
A373-A385 Pyrrolo[2,3-c]pyridine Derivatives
The pyrrolopyridine A379 might be obtained from suitably substituted 4-iodo-3-nitro-pyridines by a Sonogashira coupling, ethanolysis of the alkyne, reduction of the nitro group and TiCl4-mediated cyclization (T. Sakamoto et al., Chem. Pharm. Bull. 1986, 34, 2362-2368). The pyrrolopyridines of type A382 and A383 can be prepared from 2-methoxy-4-iodo-5-aminopyridines by Sonogashira coupling with TMS-acetylene, CuI-mediated cyclization, formylation (and oxidation) in 3-position and demethylation (D. Mazeas et al., Heterocycles 1999, 50, 1065-1080).
Pyrrolopyridines of type A384 and A385 are accessible from suitably substituted 4-methoxy-pyrrole-2-carbaldehyde by reductive amination with 3,3-diethoxy-2-amino-propionate, TiCl4-mediated cyclization and demethylation (S. K. Singh et al., Heterocycles 1997, 44, 379-392).
A386-A398 Pyrrolo[3,2-c]pyridine Derivatives
The pyrrolopyridines A387 and A388 could be accessible starting from suitably substituted N-alkylated 2-formyl-pyrroles via the 2-pyrrylacryl azides, which are then cyclized to the pyrrolopyridinones. These intermediates are then transformed into the 3-carboxy compounds via the corresponding aldehydes (J. S. New et al., J. Med. Chem. 1989, 32, 1147-1156). The pyrrolopyridines of type A389 and A390 can be obtained from suitably substituted 2-methoxy-3-formyl-pyridines by reaction with azidoacetate followed by a Hemetsberger-Knittel reaction, similarly to the synthesis of A367 and A368 (P. J. Roy et al., Synthesis 2005, 2751-2757).
A399-A413 Pyrrolo[3,2-b]pyridine Derivatives
Pyrrolopyridines of type A406 and A407 can be obtained from substituted 2-(6-methoxy-3-nitro-2-pyridyl)-acetates by Knoevenagel reaction with formaldehyde followed by Pd-catalyzed cyclization in the presence of hydrogen and CO (B. C. G. Soederberg et al., Synthesis 2008, 6, 903-912).
Pyrrolopyridines A410 and A413 can be synthesized from suitably substituted 2-chloro-3-nicotinonitriles by Sonogashira coupling with TMS-acetylene followed by ethanolysis of the alkyne and degradation of the nitrile and finally acid-induced cyclization (T. Sakamoto et al., Chem. Pharm. Bull. 1986, 34, 2362-2368). Alternatively, the synthesis of A410 and A413 can be achieved by reaction of suitably substituted 3-nitro-pyridines with vinylmagnesium bromide (Z. Zhang et al., J. Org. Chem. 2002, 67, 2345-2347). The pyrrolopyridines A408 and A412 can be obtained from 2-alkynyl-3-amino-pyridines by CuI-catalyzed cyclization (A. M. Palmer et al., Bioorg. Med. Chem. 2008, 16, 1511-1530).
A414-A449 Benzoxazole, Benzothiazole and Benzoimidazole Derivatives
Benzoxazoles A415 and A416 can be prepared starting from N-acylated 3-chloro-4-anisidines via benzyne-formation and carboxylation (D. R. Reavill, S. K. Richardson, Synth. Comm. 1990, 20, 1423-1436). The corresponding benzimidazoles A415 and A416 are accessible from of 2-amino-3-halo-benzoates by acylation of the amine, nitration in 6-position, alkylation of the amide and cyclization under reductive conditions (K. Kubo et al., J. Med. Chem. 1993, 36, 1772-1784).
Benzimidazoles of type A417-A419 can be obtained from 4-acetamido-2-methoxy-benzoates by subsequent chlorination in 5-position and nitration in 3-position, followed by reductive cyclization of the obtained 3-nitro-4-amino-benzoates in the presence of carboxylic acids or formic acid (S. Bolgunas et al., J. Med. Chem. 2006, 49, 4762-4766). This reductive cyclization procedure might also be applicable to the synthesis of other benzimidazoles. Benzimidazoles A420-A422 are accessible from the corresponding 5-methoxy-6-methyl-benzimidazoles by demethylation and oxidation of the methyl group to the carboxylate (B. D. Palmer et al., J. Med. Chem. 1999, 42, 2373-2382). Benzoxazoles of type A423-A425 can be obtained by condensation of substituted 4-methylene-2-oxazolin-5-ones and 4-triphenylphosphoranylidene-3-oxobutanoates followed by iodine-mediated aromatization (F. Clericl et al., Tetrahedron 1991, 47, 8907-8916). The synthesis of the corresponding benzimidazoles A423-A425 should be possible starting from 4-amino-2-hydroxy-5-nitrobenzoates via acylation, then reduction of the nitro group and cyclization, as is described for the 2-chloro-benzoates (A. Tanaka et al., Chem. Pharm. Bull. 1994, 42, 560-569). Benzoxazoles of type A426-A428 can be synthesized starting from 2,5-dihydroxybenzoate, which is aminated in 6-position in a multistep sequence, then acylated and cyclized (D. Diez-Martin et al., Tetrahedron 1992, 48, 7899-7939).
The benzimidazoles A429-A431 should be accessible from O-protected 3,4-diamino-2-hydroxy-benzoates, which are mono-acylated and then cyclized under acidic conditions (Y. Hirokawa et al., Chem. Pharm. Bull. 2002, 50, 941-959; A. Viger, P. B. Dervan, Bioorg. Med. Chem. 2006, 14, 8539-8549). Benzothiazoles of type A438-A440 can be synthesized by heating suitably substituted 4-amino-3-methoxy-benzoates with potassium thiocyanate in the presence of copper(II)-sulfate and subsequent 2-desamination and 3-demethylation (I. A. Ismail et al., J. Org. Chem. 1980, 45, 2243-2246). Benzimidazoles A441-A443 can be prepared by a multi-step sequence from 8-aminoquinolines via the corresponding 5,6-dihydro-4H-imidazoquinolines (R. C. Elderfield, F. J. Kreysa, J. Am. Chem. Soc. 1948, 70, 44-48). Benzimidazoles A444 and A447 can be obtained by reaction of suitably substituted 3-amino-4-methoxy-benzoates with nitriles followed by NaOCl-induced cyclization and subsequent deprotection (J. Reagn et al., Bioorg. Med. Chem. Lett. 1998, 8, 2737-2742).
A450-A459 Benzoisoxazole, Benzoisothiazole and Indazole Derivatives
Benzoisoxazoles of type A456 and A459 can be synthesized starting from 2,6-dihydroxy-3-formyl-4-methyl-benzoates by reaction with hydroxylamine followed by thermal cyclization (D. H. R. Barton et al., J. Chem. Soc. C 1971, 2166-2174). The application of this method to the synthesis of the other benzisoxazoles (A450-A455, A457 and A458) should be possible. The preparation of indazoles A457 has been described by reaction of 3-amino-2-methoxy-4-methylbenzoate with isoamylnitrite followed by demethylation (S. Bolgunas et al., J. Med. Chem. 2006, 49, 4762-4766); the application to other indazoles (A450-A456 and A458) appears feasible.
A460-A515 Naphthalene Derivatives
A relatively large number of suitably substituted naphthalene derivatives is commercially available. In addition, naphthalenes of type A460-A465 and A496-A499 can be obtained from the corresponding 2-hydroxy-naphthalenes via lithiation and carboxylation (K. Takahashi et al., Tetrahedron 1994, 50, 1327-1340). Alternatively, the demethylation of 2-methoxynaphthalene carboxylic acids has been described (Y. Gao et al., J. Med. Chem. 2001, 44, 2869-2878). Higher substituted compounds can be prepared in a multistep sequence from suitably substituted 2-bromotoluenes via 2-tetralone-1-carboxylates analogously to the method described by F. C. Goerth et al., Eur. J. Org. Chem. 2000, 2605-2612.
Naphthalenes of type A478-A483 and A508-A511 can be prepared either by demethylation of the 3-methoxynaphthalene-1-carboxylates (R. E. Royer et al., J. Med. Chem. 1995, 38, 2427-2432) or by diazotation and subsequent hydrolysis of the corresponding 3-aminonaphthalene-1-carboxylates (K. J. Duffy et al., J. Med. Chem. 2001, 44, 3730-3745).
The naphthalenes of type A484-A489 and A504-A507 can be easily built up by a condensation reaction with succinic esters, starting either from suitably substituted benzaldehydes (A. M. El-Abbady et al., J. Org. Chem. 1961, 26, 4871-4873; M. Kitamura et al., Angew. Chem. Int. Ed. 1999, 38, 1229-1232) or from benzophenones (F. G. Baddar et al., J. Chem. Soc. 1955, 1714-1718), depending on the substitution pattern in the desired product.
Naphthalene derivatives of type A490-A495 and A512-A515 can be obtained from 2-methoxynaphthalenes by bromination in 4-position, lithiation of the bromide followed by carboxylation and demethylation (J. A. O'Meara et al., J. Med. Chem. 2005, 48, 5580-5588) or from 2-chloro-naphthalene by reaction with phthalic anhydride followed by KOH-induced cleavage (G. Heller, Chem. Ber. 1912, 45, 674-679).
A516-A548 Quinoline Derivatives
The synthesis of quinolines of type A516-A518 can be accomplished by reaction of suitably substituted isatins with substituted phenacylbromides (H. John, J. Prakt. Chem. 1932, 133, 259-272; E. J. Cragoe et al., J. Org. Chem. 1953, 18, 552-560).
Quinolines of type A522-A524 are easily accessible from suitably substituted 2-amino-benzaldehydes via a modified Friedländer synthesis (D. L. Boger, J.-H. Chen, J. Org. Chem. 1995, 60, 7369-7371). Similarly, quinoline derivatives A527-A529 can be obtained from 2-aminobenzaldehydes by condensation with malonic acid (J. Troeger, C. Cohaus, J. Prakt. Chem. 1927, 117, 97-116).
Quinolines A525 can be synthesized from the corresponding 2-cyanoquinoline-1-oxides by rearrangement (C. Kaneko, S. Yamada, Chem. Pharm. Bull. 1967, 15, 663-669). The quinolines A526 (with a substitution in 4-position) are in principle accessible from substituted 2-aminoacetophenones (with the substitution on the acetyl moiety) by reaction with 3-chloro-3-oxopropionate and subsequent base-induced cyclization (A. Capelli et al., Bioorg. Med. Chem. 2002, 10, 779-802).
Quinolines of type A530-A533 can be built up starting from 2-anisidines by reaction with 2-oxosuccinic esters followed by thermal cyclization, demethylation and removal of the 4-hydroxy group via hydrogenation of the corresponding chloride (L. Musajo, M. Minchilli, Chem. Ber. 1941, 74, 1839-1843). For the synthesis of quinolines of type A543-A545 the condensation of suitably substituted isatins with malonic acid has been described (e.g. W. Borsche, W. Jacobs, Chem. Ber. 1914, 47, 354-363; J. A. Aeschlimann, J. Chem. Soc. 1926, 2902-2911).
A549-A564 Isoquinoline Derivatives
Isoquinolines of type A549-A553 with the carboxylate in the 1-position can be prepared from suitably substituted benzaldehydes, which are transformed into the aminoethanes followed by reaction with oxalic ester aldehyde or acid chloride, cyclization, oxidative aromatization and finally saponification (M. Keizo et al., Chem. Pharm. Bull. 1982, 30, 4170-4174; S, Naoki et al., Chem. Pharm. Bull. 1989, 37, 1493-1499).
Isoquinoline-3-carboxylates (A554-A556) are accessible from hydroxylated phenylalanines via a Bischler-Napieralski reaction followed by oxidative aromatization, or alternatively from suitably substituted 2-methyl benzaldehydes, which are reacted with methyl azidoacetate and then cyclized under thermal conditions followed by aromatization (Y. Fukuda et al., J. Med. Chem. 1999, 42, 1448-1458; T. R. Burke et al., Heterocycles 1992, 34, 757-764).
Compounds of type A557 and A558 can be built up by reaction between suitably substituted 2-aminobenzoic acids and 5-chloro-3-carboxy-1,2,4-pyrazines in the presence of amylnitrite followed by hydrolysis (A. M. d'A. Rocha Gonsalves, T. M. V. D. Pinho e Melo, Tetrahedron 1992, 48, 6821-6826), whereas isoquinolines A559 and A560 can be prepared by reaction of 2-formylbenzoic acids with 2-thioxothiazolidin-4-one followed by cyclization and transformation of the isothiochromenone into the isoquinoline with ethanolic ammonia (D. J. Dijksman, G. T. Newbold, J. Chem. Soc. 1951, 1213-1217).
The access to isoquinolines A561 and A562 might be possible by transformation of suitably substituted isquinolines into the corresponding Reissert compounds, nitration in 4-position and hydrolysis of the nitrile (M. Sugiura et al., Chem. Pharm. Bull. 1992, 40, 2262-2266) followed by hydrogenation of the nitro group, diazotation of the amine and transformation into the hydroxyl group.
Isoquinolines of type A563 and A564 are accessible from suitably substituted (2-methoxycarbonyl-phenyl-)acetic acids via reaction with methyl formiate followed by cyclization of the formed enol and amination of the isochromenone (H. E. Ungnade et al., J. Org. Chem. 1945, 10, 533-536).
A565-A577 Quinazoline Derivatives
The most general routes to quinazolines use appropriately substituted phenyl derivatives onto which the pyrimido ring is cyclized, e.g. the cyclocondensation of 2-amino benzamides with oxalates (M. Suesse et al., Helv. Chim. Acta 1986, 69, 1017-1024), of ortho-carbonyl substituted phenyl oxalamic acid esters with ammonium formate (S. Ferrini et al., Org. Lett. 2007, 9, 69-72), or of 2-amino benzonitriles with carbonylformimidate or chloroformamidine (A. McKillop et al., Tetrahedron Lett. 1982, 23, 3357-3360; N. Harris et al., J. Med. Chem. 1990, 33, 434-444), or of ortho-oxalyl anilides with ammonia (M. T. Bogert, F. P. Nabenhauer, J. Am. Chem. Soc. 1924, 46, 1702-1707).
A578-A587 Quinoxaline Derivatives
The synthesis of quinoxalines of types A578-581 via their 2-carbaldehydes is well-described (E. Lippmann et al., Zeitschr. Chem. 1990, 30, 251-252). The other representatives of these groups A582-587 are available by cyclocondensation of β-dicarbonyl derivatives or β-keto-esters with appropriately substituted ortho-phenylendiamines (S. Grivas et al., Acta Chem. Scand. 1993, 47, 521-528; A. Zychilinski, I. Ugi, Heterocycles 1998, 49, 29-32; D. Zhou et al., Bioorg. Med. Chem. 2008, 16, 6707-6723). Unique to the quinoxaline is the possibility to introduce a carboxyl group in the 2-position by enzyme catalyst biotransformation applying Arthrobacter nicotianae (T. Yoshida et al., Biosci. Biotech. Biochem. 2002, 66, 2388-2394).
A588-A601 Pyrido[5,4-d]pyrimidine Derivatives
The bicyclic core can be accessed by annelating suitably substituted pyridines by cyclocondensation reactions. Feasible starting materials include pyridine-2,3-dicarboxylic acids (A. Tikad et al., Synlett 2006, 12, 1938-1942), 3-aminopyridine-2-carboxylates (M. Hayakawa et al., Bioorg. Med. Chem. 2006, 14, 6847-6858) or 3-aminopyridine-2-nitriles (J. B. Smaill et al., J. Med. Chem. 2000, 43, 1380-1397).
A602-A608 Pyrimido[5,4-d]pyrimidine Derivatives
Access to the pyrimidopyrimidine group of templates might be achieved via the literature-known 4,6-dichloro derivative (G. Rewcastle et al., J. Med. Chem. 1997, 40; 12, 1820-1826) or the corresponding 2,4,6,8-tetrachloro derivative (J. Northen et al., J. Chem. Soc., Perkin Trans. 1, 2002, 108-115) using the general methods described above and separation of the expected isomeric mixtures.
A609-A618 Tetraline Derivatives
A large number of reaction sequences that lead to tetraline derivatives involve an intramolceular Friedel-Crafts acylation as a key step, and the prerequisite cyclization precusors can be elaborated from phenylacetonitriles, 2-phenyl malonates (R. S, Natekar, S. D. Samant, Indian J. Chem., Sect. B: Org. Chem. Incl. Med. Chem. 2002, 41, 187-190; L. Gong, H. Parnes, J. Labelled Compd. Radiopharm. 1996, 38, 425-434). Alternatively, the intramolecular cyclization can be achieved by a Buchner Reaction (A. Cheung et al., Bioorg. Med. Chem. Lett. 2003, 13, 133-138). Subsequently, the carbonyl groups of the thus obtained 1- or 2-tetralones can easily be converted into carboxyl moieties (M. Meyer et al., J. Med. Chem. 1997, 40, 104-1062; F. Berardi et al., J. Med. Chem. 2004, 47, 2308-2317).
A619-A626 Indane Derivatives
Indane derivatives of types A619-A623 with a carboxyl group in the 1-position are accessible from appropriately substituted and easily available 3-cyano-indenes by hydrogenation to the indane core followed by hydrolysis to the carboxylic acid moiety (T. McLean et al. J. Med. Chem. 2006, 49, 4269-4274). Also indan-1-ones can be transferred into indane-1-carboxylic acids, for example via oxiranes (D.-I. Kato et al., J. Org. Chem. 2003, 68, 7234-7242), or in a Corey-Seebach-type reaction via 1,3-dithianes (Y.-P. Pang et al., J. Org. Chem. 1991, 56, 4499-4508).
Indane derivatives of types A624-A626 with a carboxyl group in 2-position can be obtained from readily accessible, suitably substituted indan-1-ones by treatment of the corresponding enolate with a dimethyl carbonate, hydrogenation of the carbonyl group and hydrolysis of the introduced ester group (T. Tanaka et al., Chem. Pharm. Bull. 1994, 42, 1756-1759; U. Hacksell et al. J. Med. Chem. 1981, 24, 429-434). Alternatively the indane ring system can be built up starting from ortho-xylenes by NBS bromination of both methyl residues, alkylation-spirocyclization with the enolate of barbituric acid and finally decarboxylative ring cleavage to indane-2-carboxylic acids (G. A. Kraus et al., J. Org. Chem. 2002, 67, 5857-5859).
Synthesis of Building Blocks for the Modulators B
The Modulator moieties B of the macrocycle I are derived from appropriately substituted aminoalcohols, wherein the amino and alcohol group, which contribute to the ring connectivity, are separated from by 2-4 C-atoms.
If not already present in a commercial building block, the substituent R3 can be introduced by standard nucleophilic addition of organo metallic reagents to carbonyl or carboxyl derivatives. For B18-B21, carrying no additional C-substituent on their ring system, such precursors are commercially available. Similarly, in the case of B9, B10, B16 and B17 the diversification of the substituent pattern can be easily achieved by standard transformations of the commercial analogs with free amine functionalities (i.e. —NH2→NR11R27 in the case of B9 and —NH→—NR11 for B10, B16 and B17).
B1 Aziridine Derivatives
Usually, the access to hydroxymethyl aziridines relies on reaction sequences involving the construction of the aziridine ring. The starting materials with the broadest applicability are β-ketoesters: Transformation into the β-hyroxyimino analog, intramolecular cyclisation to the aziridine ring and reduction of the ester to the alcohol group leads to building blocks of type B1 (e.g. T. Sakai et al., J. Org. Chem. 2005, 70, 1369-1375). An alternative approach uses α,β-dihaloester which are converted into substances of type B1 via aziridination with ammonia and reduction of the ester group (P. Davoli et al., Tetrahedron 2001, 57, 1801-1812).
B2-B3 Azetidine Derivatives
The standard approaches to hydroxymethyl azetidines comprises subjecting easily accessible O-protected glycidols to, successively, an epoxide-ring opening with azide, transformation of the OH group of the thus obtained alcohol into a suitable leaving group (e.g. tosylate or sulfate), reduction of the azide to an amine and concomitant intramolceular cyclization (F. Hosono et al., Tetrahedron 1994, 50, 13335-13346; D.-G. Liu, G.-Q. Lin, Tetrahedron Lett. 1999, 40, 337-340).
B4-B8 Pyrrolidine Derivatives and B11-B15 Piperidine Derivatives
The synthetic approaches to the pyrrolidine and piperidine classes of building blocks B rely on the same strategies and are therefore discussed together. Intramolecular cyclization reactions are the predominant routes applicable to a broad number of diversely substituted substrates: Amines carrying a residue with a leaving group in the ω-position lead directly to the desired saturated ring systems by an intramoleular nulceophilic substitution (G. Ceulemans et al., Tetrahedron 1997, 53, 14957-14974; S. H. Kang, D. H. Ryu, Tetrahedron Lett. 1997, 38, 607-610; J. L. Ruano et al., Synthesis 2006, 687-691). Also N-haloamines can be directly transformed to the desired compounds by the Hofmann-Löffler-Freytag reaction (M. E. Wolff, Chem. Rev. 1963, 63, 55-64). Alternatively amines carrying two substituents, each with an alkene or alkyne bond, can be subjected to a ring closing metathesis (RCM) reaction (Y. Coquerel, J. Rodriguez, Eur. J. Org. Chem. 2008, 1125-1132) and subsequent reduction of the thus obtained partially unsaturated ring to the saturated heterocycle.
Also the reduction of the corresponding aromatic five- and six-membered heterocycles to their saturated analogs is described in the literature. However, due to the large number of commercially available pyridines this approach is mainly applied to the synthesis of the piperidine system (J. Bolos et al., J. Heterocycl. Chem. 1994, 31, 1493-1496; A. Solladie-Cavallo et al., Tetrahedron Lett. 2003, 44, 8501-8504; R. Naef et al., J. Agric. Food Chem. 2005, 53, 9161-9164).
Procedures for the synthesis of libraries of macrocyclic compounds of general structure I are described below but it will immediately apparent to those skilled in the art how these procedures have to be modified if it is intended to synthesize one single macrocyclic compound of formula I.
The macrocyclic compounds of the invention are obtained by cyclization of suitable linear precursors which are derived from optionally substituted hydroxyaryl, hydroxyheteroaryl, mercaptoaryl, or mercaptoheteroaryl carboxylic acids A (“template”, a), substituted amino alcohols B (“modulator”, b) and one to three building blocks of type C forming the “bridge”, c.
Variable substituents are introduced by pre- or postcyclative derivatization of one or more orthogonally protected attachment points (e.g. amino groups, carboxyl groups, hydroxyl groups) on building blocks B and C, and optionally A. Variable R-groups may also be introduced as side chain motifs in building blocks C.
The macrocyclic products of the invention can be prepared either in solution or on a solid support.
In accordance with the present invention, the ring closure reaction is, in principle, possible between any of the building blocks.
Macrocycles of general structure I with building block c forming the bridge c are obtained by either

    a) macrolactamisation between c and B; or
    b) macrolactamisation between A and c; or
    c) aryl- or thioaryl ether formation between A and B; or, alternatively,
    d) Ring closure metathesis reaction within building blocks of type C is also possible.


Macrocycles of structure I with orthogonally protected exocyclic functional groups (attachment points for derivatization) are prepared in solution by a process which comprises:

    a1) condensation of an appropriately protected hydroxy- or mercapto-aryl/heteroaryl carboxylic acid PG-A-OH and a suitably C-terminal- and appropriately side-chain-protected building block H-c1-OPG to form PG-A-c1-OPG;
    b1) if required release of the aryl/heteroaryl (phenolic) OH group or mercapto group, respectively;
    c1) aryl/heteroaryl ether or thioether formation with a suitably N-protected amino alcohol HO—B-PG leading to the fully protected linear cyclization precursor PG-B-A-c1-OPG;
    d1) cleavage of the “main chain” protective groups (PG) affording the free amino acid H—B-A-c1-OH (still carrying appropriately protected side chain functional groups); followed by either


e1) intramolecular amide coupling affording protected macrocycles of general formula I (yielding cyclo-(B-A-c1) still carrying orthogonally protected side chain functional groups); or

    f1) N-reprotection of the product obtained in step d1);
    g1) coupling of a suitably C-protected amino acid H-c2-OPG;
    h1) cleavage of the “main chain” protective groups affording the free amino acid H—B-A-c1-c2-OH (still carrying appropriately protected side chain functional groups);
    i1) intramolecular amide coupling affording the protected macrocycles of general formula I (yielding cyclo-(B-A-c1-c2); still carrying orthogonally protected side chain functional groups); or
    j1) N-protection of the product obtained in step d1);
    k1) coupling of a suitably C-protected amino acid H-c2-OPG
    l1) cleavage of the C-terminal protective group or cleavage of N- and C-terminal main chain protective groups and reprotection of the N-terminus;
    m1) coupling of a suitably C-protected amino acid H-c3-OPG;
    n1) release of the “main chain” protective groups affording the free amino acid H—B-A-c1-c2-c3-OH (still carrying protected side chain functional groups); and
    o1) intramolecular amide coupling affording the protected macrocycles of general formula I (yielding cyclo-(B-A-c1-c2-c3), still carrying protected side chain functional groups).


The appropriately protected, preferably acyloxy- or acylmercapto-, most preferably acetyloxy- or acetylmercapto-substituted aryl/heteroaryl carboxylic acid (PG1-A-OH) is converted into the corresponding acid chloride and condensed with a suitably protected amino acid ester

    H-c1-OPG2 in the presence of an auxiliary base (e.g i-Pr2NEt, Et3N, pyridine, collidine) and in solvents like CH2Cl2, CHCl3, THF to afford after deacylation (preferably by aminolysis) the hydroxyl or mercapto aryl/heteroaryl amide H-A-c1-OPG2.


The aminolysis is advantageously carried out with a dialkylaminoalkyl amine in solvents like THF at 0-25° C. Acyl amine side products formed in the course of the reaction can thus be removed by extraction with acidic aqueous solutions.
Alternatively, the acyloxy or acylmercapto aryl/heteroaryl carboxylic acid (PG1-A-OH) can be coupled in the presence of a coupling reagent (such as benzotriazol derivatives like HBTU, HCTU, PyBOP, or their aza analogs such as HATU, or carbodiimides such as EDC) to the amino acid ester H-c1-OPG2 to afford, after deacylation, the phenol or thiophenol H-A-c1-OPG2.
The phenol H-A-c1-OPG2 can also be directly obtained from the hydroxyaryl/heteroaryl carboxylic acid H-A-OH and the amino acid ester H-c1-OPG2 in the presence of a coupling reagent.
Alkylation of the phenol or thiophenol H-A-C1—OPG2 with a suitably N-protected amino alcohol HO—B-PG3 to give the ether or thioether

    PG3-B-A-c1-OPG2 is achieved using azodicarboxylic acid derivatives such as DEAD, DIAD or ADDP in the presence of trialkyl or triaryl phosphines in solvents like benzene, toluene, CH2Cl2, CHCl3 or THF at 0° C. to room temperature. As a variation, the reaction can be induced with CMBP in toluene at temperatures ranging from 20-110° C.


As an alternative, the alcohol HO—B-PG3 can be converted into a corresponding sulfonates (such as for example the mesylate, tosylate, triflate) or a corresponding halide (such as chloride, bromide and iodide) and subsequently be treated with the phenol or thiophenol

    H-A-c1-OPG2 in the presence of an auxiliary base such as for example NaH or K2CO3 in solvents like DMF, DMSO, NMP, HMPA, THF, to give the ether or thioether PG3-B-A-c1-OPG2.


Simultaneous or stepwise cleavage of the main chain protective groups provides the linear amino acid cyclization precursor H-B-A-c1-OH. Alloc (for PG3) and allylester groups (for PG2) are preferred as protecting groups and best cleaved simultaneously mediated by palladium catalysts, e.g. Pd(PPh3)4, in the presence of 1,3-dimethyl barbituric acid in solvents like CH2Cl2 or EtOAc or mixtures thereof.
Macrolactamization occurs upon treatment of the cyclization precursor

    H—B-A-c1-OH—if required in the presence of an auxiliary base such as i-Pr2NEt—with coupling reagents like T3P or FDPP in solvents like CH2Cl2 or DMF under high dilution conditions and at temperatures ranging from 20 to 100° C. to yield cyclo-(B-A-c1).


For examples of macrolactamizations mediated by FDPP see J. Dudash, J. Jiang, S. C. Mayer, M. M. Joullié, Synth. Commun. 1993, 23 (3), 349-356; R. Samy, H. Y. Kim, M. Brady, and P. L. Toogood, J. Org. Chem. 1999, 64, 2711-2728.
It is well known that many other coupling reagents have been used in such head to tail cyclizations to prepare macrolactams, and such other coupling reagents might, alternatively, be engaged in the above mentioned reactions. Examples include benzotriazole derivatives such as HBTU, HCTU, PyBOP and their aza analogs such as HATU, as well as DPPA, and carbodiimides like EDC, DIPCDI; for examples see P. Li, P. P. Roller, Current Topics in Mecicinal Chemistry 2002, 2, 325-341; D. L. Boger, S. Miyazaki, S. H. Kim, J. H. Wu, S. L. Castle, O. Loiseleur, and Q. Jin, J. Am. Chem. Soc. 1999, 121, 10004-10011).
Another option to obtain macrolactams comprises the intramolecular reaction of an active ester with an in situ released amino group (carbamate deprotection, azide reduction) as demonstrated for example in the synthesis of peptide alkaloids and vancomycin model systems (U. Schmidt, A. Lieberknecht, H. Griesser, J. Talbiersky, J. Org. Chem. 1982, 47, 3261-3264; K. C. Nicolaou, J. M. Ramanjulu, S, Natarajan, S. Bräse, H. Li, C. N. C. Boddy, F. Rubsam, Chem. Commun. 1997, 1899-1900.)
N-reprotection of H—B-A-c1-OH can be achieved applying standard amino acid protection protocols. Chloroformates or N-hydroxy-succinimidyl carbonates in solvents like dioxane, if required in the presence of a base such as aqueous K2CO3 solution, react to give the N-protected amino acid PG3-B-A-c1-OH.
Coupling of an additional amino acid can be effected applying classical peptide coupling conditions.
Building blocks c1-c3 can be derived from tri-functionalized aminoacids (e.g. derivatives of Dap, Dab, Orn, Lys, Asp, Glu), main chain- or side chain-functional groups of which may be part of the macrocyclic scaffold.
Non proteinogenic tri-functionalized amino acid building blocks can be obtained by various synthetic methods, among others formal alkylation of the side chain hydroxyl group of Ser, HomoSer, Thr or derivation of the mercapto group of Cys, HomoCys with Ω-haloalkyl carboxylic esters.
An alternative route for synthesizing macrocyclic compounds of the invention comprises

    a2) synthesis of the H-A-c1-OPG2 fragment as described above;
    b2) N-acylation of the aminoalcohol HO—B—H with a suitably N-terminal protected amino acid PG4-c2-OH to afford the amidoalcohol PG4-c2-B—OH;
    c2) aryl or thioaryl ether synthesis starting from H-A-c1-OPG2 and PG4-c2-B—OH, applying conditions as described above;
    d2) release of the “main chain” protective groups to give the cyclization precursor H-c2-B-A-c1-OH; and
    e2) macrolactamization as described above, affording the protected macrocycles of general formula I (cyclo-(c2-B-A-c1), side chain functional groups still carrying orthogonal protective groups).


The fragment PG4-c3-B—OH can be prepared by N-Acylation of the amino alcohol HO—B—H with suitable N-terminal protected amino acid PG4-C3-OH. N-deprotection and coupling to an appropriately N-terminal protected amino acid PG5-c2-OH affords the alcohol PG5-c2-c3-B—OH which can then be converted—by effecting steps corresponding to c2), d2) and e2)—into the protected macrocycles of general formula I (cyclo(c2-c3-B-1′-c1), side chain functional groups still carrying orthogonal protective groups).
As a further alternative, cyclization can be obtained by ring closing metathesis. The orthogonally protected macrocycles of general structure I are synthesized applying a process which comprises

    a3) coupling of an optionally substituted alkenyl amine containing building block c1(alkenyl) of type C to the acyloxy or hydroxy or acylmercapto aryl/heteroaryl carboxylic acid PG1-A-OH;
    b3) if required release of the aryl/heteroaryl (phenolic) OH group or mercapto group, respectively;
    c3) N-acylation of the aminoalcohol HO—B—H with an optionally suitably substituted alkenyl carboxylic acid PG6-c2(alkenyl)-OH to afford the amido alcohol PG6-c2(alkenyl)-B—OH;
    d3) aryl or thioaryl ether formation as described above to yield the cyclization precursor PG6-c2(alkenyl)-B-A-c1(alkenyl);
    e3) ring closure metathesis; and
    f3) optional hydrogenation of the newly generated olefinic double bond of the metathesis product of step e3).


Ring closure metathesis to form macrocyclic compounds from olefinic precursors is well known (for examples see A. Fürstner, O. Guth, A. Duffels, G. Seidel, M. Liebl, B. Gabor, and R. Mynott, Chem. Eur. J. 2001, 7 (22), 4811-4820).
Ring closure metathesis of PG6-c2(alkenyl)-B-A-c1(alkenyl) is conveniently performed in suitable solvents, like CH2Cl2 or toluene, at 20 to 100° C. in the presence of indenylidene-ruthenium complexes including dichloro-(3-phenyl-1H-inden-1-ylidene)bis(tricyclohexylphosphine)-ruthenium (II), [1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene]-dichloro-(3-phenyl-1H-inden-1-ylidene(tricyclohexylphosphine)-ruthenium(II), [1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene]-dichloro-(3-phenyl-1H-inden-1-ylidene) (pyridyl)ruthenium(II) (see S. Monsaert, R. Drozdzak, V. Dragutan, I. Dragutan, and F. Verpoort, Eur. J. Inorg. Chem. 2008, 432-440 and references therein).
Derivatization of the macrocyclic core structures with variable R-groups can be effected as described hereinbelow.
Orthogonally protected attachment points (e.g. exocyclic amino groups, carboxyl groups, hydroxyl groups) allow stepwise deprotection and derivatization.
The reactions can be carried out in a parallel fashion to generate libraries of final products. The following general process can be applied:

    a4) Cleavage of the first protective group;
    b4) derivatization of the free functional group;
    c4) cleavage of the second protective group, and
    d4) derivatiszation or the free functional group.


Amine protecting groups such as preferably Boc, Cbz, Teoc, Alloc, Fmoc are removed applying standard conditions, cf. T. W. Greene, P. G. M. Wuts, Protective Groups in Organic Synthesis, 3rd edition, John Wiley & Sons, 1999; P. J. Koncienski, Protecting Groups, 3rd edition, Georg Thieme Verlag, 2005. Carboxylic acid protecting groups such as tert.butyl, benzyl, allyl, methyl are removed applying standard conditions.
Alcohol protecting groups such as tert.butyl, benzyl, allyl, acetyl, benzoyl, pivaloyl are removed applying standard conditions.
Attachment point amino groups can be converted into amides by reaction with carbonyl chlorides, carboxylic acid anhydrides active esters or by treatment with carboxylic acids in the presence of soluble or polymer-supported coupling reagents such as for example HATU, T3P or polymer-supported carbodiimides.
Reductive alkylation of the attachment point amino groups or their reaction with alkyl halides, alkylsulfonates or Michael acceptors affords higher alkylated amines.
The reaction of attachment point amino groups with isocyanates or equivalents like carbamoyl chlorides or hydroxysuccinimidyl esters affords ureas.
The reaction of attachment point amino groups with isothiocyanates provides thioureas.
The reaction of attachment point amino groups with chloroformates or equivalents such as hydroxysuccinimidyl carbonates affords carbamates.
The reaction of attachment point amino groups with sulfonyl chlorides yields sulfonamides.
The reaction of attachment point amino groups with suitably activated aromatic or heteroaromatic halides or sulfonates—in the presence of auxiliary base and if required a Pd catalyst (e.g. Buchwald couplings)—affords the corresponding N-aryl or N-heteroaryl derivatives.
Attachment point carboxyl groups are converted into amides using amines and coupling reagents.
Attachment point alcoholic hydroxyl groups can be alkylated with alkyl halides or alkylsulfonates to give alkylethers. Their reaction with phenols in the presence of azodicarboxylic acid derivatives and triaryl or trialkyl phosphines as well as their reaction with suitably activated aryl or heteroaryl halides or sulfonates affords aryl or heteroaryl ethers.
Attachment point secondary alcoholic hydroxyl groups can be oxidized to the corresponding ketones which in turn may be submitted to a reductive amination using amines and a suitable reducing agent.
Attachment point alcoholic hydroxyl groups can be converted into esters.
Appropriate macrocyclic compounds of general formula I with one or more (orthogonally) protected exocyclic functional groups and a free primary amino group can be converted into fully derivatized products on solid support.
A process, which allows an efficient parallel array derivatization, comprises

    a5) attachment of the macrocyclic amine to an appropriately functionalized solid support in a reductive amination step;
    b5) acylation, carbamoylation, oxycarbonylation or sulfonylation of the secondary amine thus obtained in step a5);
    c5) Removal of the protective group of the next attachment point;
    d5) Derivatisation of the second free functional group whereby amino groups can be converted into amides, ureas, thioureas carbamates, or sulfonamides, or can be alkylated; and carboxylic acids can be converted into amides;
    e5) repetition of steps c5) and d5) if an additional derivatisation site is available; and
    f5) Release of the final product from solid support.


In principle a macrocyclic carbocylic acid can be coupled to polymer-supported amines and be converted into final products by effecting steps corresponding c5) to f5).
The functionalized solid support is a derivative of polystyrene cross-linked with preferably 1-5% divinylbenzene, of polystyrene coated with polyethyleneglycol (Tentagel®), and of polyacrylamid resins (see D. Obrecht, J.-M. Villalgordo, “Solid-Supported zombinatorial and Parallel Synthesis of Small-Molecular-Weight Compound Libraries”, Tetrahedron Organic Chemistry Series, Vol. 17, Pergamon, Elsevier Science, 1998).
The solid support is functionalized by means of a linker, i.e. a bifunctional spacer molecule which contains on one end an anchoring group for attachment to the solid support and on the other end a selectively cleavable functional group used for the subsequent chemical transformations and cleavage procedures. For the purposes of the present invention, linkers are used which are designed to release an N-acyl derivative (amide, urea, carbamate) or a sulfonamide under acidic conditions. Such linkers have been applied in the backbone amide linker (BAL) strategy for solid-phase synthesis of C-terminal modified and cyclic peptides (K. J. Jensen, J. Alsina, M. F. Songster, J. Vagner, F. Albericio, and G. Barnay, J. Am. Chem. Soc. 1998, 120, 5441-5452; J. Alsina, K. J. Jensen, F. Albericio, and G. Barany, Chem. Eur. J. 1999, 5 (10), 2787-2795) as well as for the synthesis of heterocyclic compounds (T. F. Herpin, K. G. Van Kirk, J. M. Savino, S. T. Yu, and R. F. Labaudinière, J. Comb. Chem. 2000, 2, 513-521, M. del Fresno, J. Alsina, M. Royo, G. Barany, and F. Albericio, Tetrahedron Lett. 1998, 39, 2639-2642; N. S. Gray, S. Kwon, P. G. Schultz, Tetrahedron Lett. 1997, 38 (7), 1161-1164).
Examples of resins functionalized by such linker structures include DFPE polystyrene (2-(3,5-dimethoxy-4-formylphenoxy)ethyl polystyrene), DFPEM polystyrene (2-(3,5-dimethoxy-4-formylphenoxy)ethoxymethyl polystyrene), FMPB resins (4-(4-formyl-3-methoxyphenoxy)butyryl AM resin), FMPE polystyrene HL (2-(4-formyl-3-methoxyphenoxy)ethyl polystyrene HL), FMPB NovaGelTM (4-(4-formyl-3-methoxyphenoxy)butyryl NovaGelTM; a PEG PS resin).
The macrocyclic primary amine is attached to such solid support by means of reductive amination preferably using NaBH(OAc)3 in 1,2 dichloroethane in the presence of trimethyl orthoformate.
The use of reductive amination to couple amines to resins with the above mentioned linker is well documented; for example NaBH3CN in DMF or in methanol, or NaBH(OAc)3 in DMF/acetic acid or in dichloromethane/acetic acid have been used (see K. J. Jensen, J. Alsina, M. F. Songster, J. Vagner, F. Albericio, and G. Barany, J. Am. Chem. Soc. 1998, 120, 5441-5452; J. Alsina, K. J. Jensen, F. Albericio, and G. Barnay, Chem. Eur. J. 1999, 5 (10), 2787-2795; T. F. Herpin, K. G. Van Kirk, J. M. Savino, S. T. Yu, and R. F. Labaudinière, J. Comb. Chem. 2000, 2, 513-521; A. L. Vergnon, R. S. Pottorf, M. R. Player, J. Comb. Chem. 2004, 6, 91-98.). These authors also describe a variety of conditions for the acylation of the resulting secondary amine, using carboxylic acid and coupling reagents including PyBOP, PyBroP, HATU as well as carboxylic acid fluorides or carboxylic acid anhydrides.
The second functional group is an Alloc or Fmoc protected amino group or a carboxyl group protected as allyl ester. Standard conditions are applied to deprotect and derivatize these functional groups.
The final products are detached from the solid support by means of acid in organic solvents or in H2O. The use of TFA in dichloromethane, TFA in dichloromethane in the presence of a scavenger such as H2O or dimethyl sulfide, or of TFA/H2O and TFA/H2O/dimethylsulfide has been described, references see above.
Macrocyclic compounds of general formula I with highly variable amino acid side chain motifs in bridge c can advantageously be prepared in a parallel array synthesis on solid support. This synthesis comprises immobilization of an appropriately protected and functionalized precursor comprising building blocks A, B and subsequent coupling of one to three amino acids c1, c2 and c3, followed by cyclization and release of the product thus obtained.
The corresponding process comprises:

    a6) condensation of a suitable hydroxy or mercapto aryl/heteroaryl carboxylic acid ester H-A-OPG7 with an appropriately N-protected amino alcohol HO—B-PG8, substituted with an orthogonally protected primary amino group, applying the methods discussed above;
    b6) removal of the protective group of the primary amine;
    c6) attachment of the product obtained in step b6) to the solid support in a reductive alkylation step in analogy to the previously described process providing a polymer-supported fragment PG8-B-A-O-PG7 with free secondary side chain amino group;
    d6) acylation, carbamoylation, oxycarbonylation or sulfonylation of the secondary amine obtained in step c6);
    e6) cleavage of the “main chain” amine protective group (PG8);
    f6) coupling of a appropriately N-terminal protected amino acid PG9-c3-OH;
    g6) removal of the N-terminal protective group (PG9) of the product obtained in step f6);
    h6) next coupling to introduce amino acid PG9-c1-OH (for target compounds with bridges comprising two amino acid building blocks), or coupling/deprotection cycle to introduce amino PG9-c2-OH followed by coupling of amino acid PG9-c1-OH (for target compounds with bridges comprising three amino acid building blocks) by effecting steps corresponding to f6) and g6);
    i6) cleavage of the aryl/heteroaryl ester group (PG7);
    j6) cleavage of the N-terminal protective group (PG9);
    k6) macrolactamization of the linear cyclization precursor on solid support (for an example of cyclization on solid support see the synthesis of cyclic peptides attached to the solid support with the side chain as described by C. Cabrele, M. Langer, and A. G. Beck-Sickinger, J. Org. Chem. 1999, 64, 4353-4361.); and
    l6) detachment of the final product.


As an alternative, the linear cyclization precursor obtained in step j6) can be released from the solid support and cyclized in solution by

    k6′) detachment of the linear cyclization precursor; and
    l6′) macrolactamization in solution.


In a parallel array synthesis soluble coupling reagents as described above as well as polymer supported coupling reagents such as N-cyclohexyl-carbodiimide-N′-methylpolystyrene or N-alkyl-2-chloro pyridinium triflate resin (S. Crosignani, J. Gonzales, D. Swinnen, Org. Lett. 2004, 6 (24), 4579-4582) may be used.
Further alternatives include ring closure in other positions, for example between amino acids c1 and c2.
Thus a precursor with two amino acids coupled to the immobilized precursor would be prepared (polymer supported PG9-c2-c3-B-A-OPG7) by effecting steps corresponding to steps a6) to h6) described in the above paragraph. The subsequent steps then comprise

    i6′) cleavage of the aryl/heteroaryl ester group (PG7);
    j6′) coupling of an appropriately C-terminal protected amino acid
    H-c1-OGP7;
    k6′) cleavage of the c-terminal protective group (PG7);
    l6′) cleavage of the N-terminal protective group (PG9) and
    m6′) macrolactamization either on solid support or in solution after detachment of the linear precursor from the solid support.


The macrocycles of formula I of the present invention interact with specific biological targets. In particular, they show agonistic or antagonistic activity on the motilin receptor (MR receptor), on the serotonin receptor of subtype 5-HT2B (5-HT2B receptor), and on the prostaglandin F2α receptor (FP receptor). Accordingly, these compounds are useful for the treatment of hypomotility disorders of the gastrointestinal tract such as diabetic gastroparesis and constipation type irritable bowl syndrome; for the treatment of CNS related diseases like migraine, schizophrenia, psychosis or depression; for the treatment of ocular hypertension such as associated with glaucoma and for preterm labour.
The macrocycles, as such or after further optimization, may be administered per se or may be applied as an appropriate formulation together with carriers, diluents or excipients well-known in the art.
When used to treat or prevent the diseases mentioned above the macrocycles can be administered singly, as mixtures of several macrocycles, or in combination with other pharmaceutically active agents. The macrocycles can be administered per se or as pharmaceutical compositions.
Pharmaceutical compositions comprising macrocycles of the invention may be manufactured by means of conventional mixing, dissolving, granulating, coated tablet-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes. Pharmaceutical compositions may be formulated in conventional manner using one or more physiologically acceptable carriers, diluents, excipients or auxiliaries which facilitate processing of the active macrocycles into preparations which can be used pharmaceutically. Proper formulation depends upon the method of administration chosen.
For topical administration the macrocycles of the invention may be formulated as solutions, gels, ointments, creams, suspensions, etc. as are well-known in the art.
Systemic formulations include those designed for administration by injection, e.g. subcutaneous, intravenous, intramuscular, intrathecal or intraperitoneal injection, as well as those designed for transdermal, transmucosal, oral or pulmonary administration.
For injections, the macrocycles of type I may be formulated in adequate solutions, preferably in physiologically compatible buffers such as Hank's solution, Ringer's solution, or physiological saline buffer. The solutions may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Alternatively, the macrocycles of the invention may be in powder form for combination with a suitable vehicle, e.g., sterile pyrogen-free water, before use.
For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation as known in the art.
For oral administration, the compounds can be readily formulated per se or by combining the active macrocycle of the invention with pharmaceutically acceptable carriers well known in the art. Such carriers enable the macrocycles of type I to be formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions etc., for oral ingestion by a patient to be treated. For oral formulations such as, for example, powders, capsules and tablets, suitable excipients include fillers such as sugars, (e.g. lactose, sucrose, mannitol or sorbitol) or such as cellulose preparations (e.g. maize starch, wheat starch, rice starch, potato starch, gelatin, gum tragacanth, methyl cellulose, hydroxypropylmethyl cellulose, sodium carboxymethylcellulose); and/or granulating agents; and/or binding agents such as polyvinylpyrrolidone (PVP). If desired, desintegrating agents may be added, such as cross-linked polyvinylpyrrolidones, agar, or alginic acid or a salt thereof, such as sodium alginate. If desired, solid dosage forms may be sugar-coated or enteric-coated using standard techniques.
For oral liquid preparations such as, for example, suspensions, elixirs and solutions, suitable carriers, excipients or diluents include water, glycols, oils, alcohols, etc. In addition, flavoring agents, preservatives, coloring agents and the like may be added.
For buccal administration, the composition may take the form of tablets, lozenges, etc. formulated as usual.
For administration by inhalation, the macrocycles of the invention are conveniently delivered in form of an aerosol spray from pressurized packs or a nebulizer, with the use of a suitable propellant, e.g. hydrofluoroalkanes (HFA) such as HFA 134a (1,1,1,2,-tetrafluoroethane); carbon dioxide or another suitable gas. In the case of a pressurized aerosol the dose unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of e.g. gelatin for use in an inhaler or insufflator may be formulated containing a powder mix of the macrocycles of the invention and a suitable powder base such as lactose or starch.
The compounds may also be formulated in rectal or vaginal compositions such as suppositories together with appropriate suppository bases like cocoa butter or other glycerides.
In addition to the formulations described afore, the macrocycles of the invention may also be formulated as depot preparations. Such slow release, long acting formulations may be administered by implantation (e.g. subcutaneously or intramuscularly) or by intramuscular injection. For the manufacture of such depot preparations the macrocycles of the invention may be formulated with suitable polymeric or hydrophobic materials (e.g. as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble salts.
In addition, other pharmaceutical delivery systems may be employed such as liposomes and emulsions well known in the art. Certain organic solvents such as dimethylsulfoxide may also be employed. Additionally, the macrocycles of type I may be delivered using a sustained-release system, such as semi-permeable matrices of solid polymers containing the therapeutic agent. Various sustained-release materials have been established and are well-known by those skilled in the art. Sustained-release capsules may, depending on their chemical nature, release the compounds over a period of a few days up to several months. Depending on the chemical nature and the biological stability of the therapeutic agent, additional strategies for stabilization may be employed.
As the macrocycles of the invention may contain charged residues, they may be included in any of the above-described formulations as such or as pharmaceutically acceptable salts. Pharmaceutically acceptable salts tend to be more soluble in aqueous and other protic solvents than the corresponding free base or acid forms.
The macrocycles of the invention, or compositions thereof, will generally be used in an amount effective to achieve the intended purpose. It is to be understood that the amount used will depend on a particular application.
For example, the therapeutically effective dose for an systemic administration can be estimated initially from in vitro assays: A dose can be formulated in animal models to achieve a circulating macrocycle concentration range that includes the IC50 or EC50 as determined in the cell culture (i.e. the concentration of a test compound that shows half maximal inhibitory concentration in case of antagonists or half maximal effective concentration in case agonists). Such information can be used to more accurately determine useful doses in humans. Initial dosages can also be determined from in vivo data, e.g. animal models, using techniques that are well known in the art. One having ordinary skill in the art could readily optimize administration to humans based on animal data.
Dosage amounts for applications such as gastroparesis or schizophrenia etc. may be adjusted individually to provide plasma levels of the active compound that are sufficient to maintain the therapeutic effect. Therapeutically effective serum levels may be achieved by administering multiple doses each day.
In cases of local administration or selective uptake, the effective local concentration of the macrocycles of the invention may not be related to plasma concentration. Those having the ordinary skill in the art will be able to optimize therapeutically effective local dosages without undue experimentation.
The amount of macrocycle administered will, of course, be dependent on the subject being treated, on the subject's weight, the severity of the affliction, the manner of administration and the judgment of the prescribing physician.
Normally, a therapeutically effective dose of the macrocycles described herein will provide therapeutic benefit without causing substantial toxicity.
Toxicity of the macrocycles of the invention can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., by determining the LD50 (the dose lethal to 50% of the population) or the LD100 (the dose lethal to 100% of the population). The dose ratio between toxic and therapeutic effect is the therapeutic index. Compounds which exhibit high therapeutic indices are preferred. The data obtained from cell culture assays and animal studies can be used in formulating a dosage range that is not toxic for use in humans. The dosage of the macrocycles of the invention lies preferably within a range of circulating concentrations that include the effective dose with little or no toxicity. The dosage may vary within the range depending upon the dosage form employed and the route of administration utilized. The exact formulation, route of administration and dose can be chosen by the individual physician in view of the patient's condition (cf. E. Fingl et al., The Pharmacological Basis of Therapeutics, 5th ed. 1975 (Ed. L. Goodman and A. Gilman), Ch.1, p. 1).
A further embodiment of the present invention may also include compounds, which are identical to the compounds of formula I, except that one or more atoms are replaced by an atom having an atomic mass number or mass different from the atomic mass number or mass usually found in nature, e.g. compounds enriched in 2H (D), 3H, 11C, 14C, 125I etc. These isotopic analogs and their pharmaceutical salts and formulations are considered useful agents in the therapy and/or diagnostic, for example, but not limited to, where a fine-tuning of in vivo half-life time could let to an optimized dosage regimen.

Biological Methods

1. Preparation of the Example Compounds

Example compounds were weighed on a Microbalance (Mettler MX5) and dissolved in 100% DMSO to a final concentration of 2.5 mM for Ca2+ assays.
Example compounds were dissolved in DMSO/H2O 90:10 to a final concentration of 10 mM for plasma stability determination and metabolic stability determination.
2. Ca2+ Assays: GPCR Assays for Motilin Receptor, Prostaglandin F (FP) Receptor and 5-Hydroxytryptamine 2B (5-HT2B) Receptor
Assays were performed using a FLIPR Tetra (Molecular Devices); the data analysis and FLIPR Tetra Operating-Soft ware was ScreenWorks version 2 (Molecular Devices).
Dose dependent agonist and antagonist activities were determined. Percentage activation and percentage inhibition values were determined.
Percentage activation was determined upon initial addition of the sample compounds followed by 10 minutes incubation at 25° C. Following compound incubation, reference agonists were added at EC80 to determine percentage inhibition.
Reference agonists were purchased from reputable commercial vendors and prepared according to specifications specific to each ligand. All handling of ligands were done to ensure proper control throughout the experiments.
Test compounds were serially diluted with DMSO. Once the appropriate concentrations were attained, the compounds were diluted into assay buffer.
GPCR Assay Buffer:
Assay buffer was a supplemented HBSS (Hank's Balanced Salt Solution). HBSS was supplemented with 20 mM HEPES (4-(2-hydroxyethyl)-piperazin-1-ethansulfonic acid) and 2.5 mM Probenecid (Sigma P8761).
Assay Plate Seeding:
GPCR assays were performed using Ca2+ optimized hematopoietic cell lines (rat) with cultures never exceeding 90% confluency. Cells were harvested and seeded (from cultures at less than 90% confluency) at 50000 cells/well for a 96-well plate (12500 cells/well for 384). After seeding, the assay plates were incubated for forty-five (45) minutes at room temperature. After room temperature incubation, the assay plates were incubated at 37° C. 5% CO2 for 24 hours prior to assaying.
Calcium Dye Loading:
All GPCR assays were performed using Fluo-8 Ca2+ dye. Ca2+ dye was prepared at 1× dye concentration in GPCR assay buffer. After 24 hours of incubation, cells were washed with GPCR assay buffer, then Ca2+-dye (100 μL/well) was added. The plates were incubated for 90 minutes at 30° C. 5% CO2 prior to FLIPR assay.
Agonist Assay:
Compound plates were prepared to add 50 μL/well during the agonist assay mode. During the FLIPR assay, 50 μL/well from the compound plate was diluted 3-fold into the existing 100 μL/well from the dye loading step. Therefore all compounds were prepared as 3× the final concentration desired in the assay.
After completion of the first single addition assay run, assay plate was removed from the FLIPR Tetra and placed at 25° C. for seven (7) minutes before antagonist assay.
Antagonist Assay:
Using the EC80 values determined during the agonist assay, all pre-incubated sample compound and reference antagonist (if applicable) wells were stimulated with EC80 of reference agonist (motilin; prostaglandin F2α).
After the addition of the reference agonist fluorescence was monitored for 180 sec using FLIPR Tetra.
Data Analysis:
From the FLIPR data, with negative control correction enabled, the maximum statistic for each well was exported and percentage activation relative to Emax control was calculated.
3. Plasma Stability
Human plasma (3-5 donors, Blutspendedienst SRK, Basel) and CD-1 mouse plasma (mixed gender pool>50 animals, Innovative Research, CA, USA) are both sodium citrate stabilized. The assay is performed in triplicates at 10 μM compound concentration and 37° C. Samples are taken at 0, 15, 60, and 240 minutes and stopped by precipitation with 2 volumes of acetonitrile. The supernatant is collected, evaporated and reconstituted in a 5% acetonitrile solution to be analyzed by HPLC/MS/MS. The resulting peak area counts are expressed in percent of the 0 value and used to determine the endpoint stability in % and the half life T1⁄2 in minutes. In order to monitor assay integrity the degradation of propantheline is assayed with every experimental set
4. Metabolic Stability
Microsomes from a human 50 donor mixed gender pool and 1:1 mixtures of microsomes from CD-1 mouse single-gender pools are purchased from Celsis (Belgium). The enzymatic reaction is performed in a buffer containing an NADPH regeneration system and microsomes with the following end concentrations: 100 mM potassium phosphate buffer (all from Sigma), 1 mg/mL glucose-6-phosphate, 1 mg/mL β-nicotinamide adenine dinucleotide phosphate (NADP), 0.65 mg/mL magnesium chloride, 0.8 units/mL of glucose-6-phosphate dehydrogenase (prediluted with 5 mM citrate buffer), 10 μM compound and 1 mg/ml microsomal protein. Compounds are incubated at 37° C. in duplicates and samples are taken after 0, 20 and 60 minutes. After acetonitrile precipitation (2 volumes) and HPLC/MS/MS analysis metabolic turnover is expressed in % of the initial 0 minutes value and half life T1⁄2 (min) is calculated. Verapamil for human and propranolol for mouse are used as reference and are assayed with every experimental set.
