Delay‐range‐dependent H∞ control for Markovian jump systems with mode‐dependent time delays
Authors: Wang Guoliang , Zhang Qingling , Sreeram Victor 
Published: June 2010

AbstractThis paper considers mean‐square exponential stability and H∞ control problems for Markovian jump systems (MJSs) with time delays which are time‐varying in an interval and depend on system mode. By exploiting a novel Lyapunov‐Krasovskii functional which takes into account the range of delay, and by making use of some techniques, new delay‐range‐dependent stability result and bounded real lemma for MJSs are obtained, where the introduction of the lower bound of delay is shown to be advantageous for reducing conservatism. Moreover, a sufficient condition for the solvability of the H∞ control problem is derived in terms of linear matrix inequalities. Finally, illustrative examples are presented to show the advantage and effectiveness of the proposed approaches.

AbstractDie Kondensation von 2‐Thio‐hydrazo‐dicarbonamid mit α‐halogenierten Ketoverbindungen führt zu einer neuen Stoffklasse, den 1‐[Thiazolyl‐(2)]‐semicarbaziden. Die verschieden substituierten Verbindungen wurden durch Mono‐ bzw. Diacetylderivate charakterisiert. Bei der Einwirkung von konz. Salpetersäure auf 1‐[4‐Phenyl‐thiazolyl‐(2)]‐semicarbazid entsteht [4‐(p‐Nitro‐phenyl)‐thiazolyl‐(2)]‐azo‐carbonamid.
Zur Reduktion von Pyridin‐Derivaten mit Lithiumaluminiumhydrid
Authors: Bohlmann Ferdinand , Bohlmann Magdalene 
Published: June 2010

AbstractWerden Pyridin‐Derivate, die in 3‐ und 5‐Stellung Ester‐ oder Cyangruppen tragen, mit Lithiumaluminiumhydrid reduziert, so wird zuerst der Ring angegriffen. Dagegen werden bei 2.4‐ und 6‐substituierten Pyridinen die funktionellen Gruppen reduziert, ohne daß der Kern in Mitleidenschaft gezogen wird. Die Unterschiede lassen sich durch die verschiedene Polarisierung der Pyridin‐Derivate erklären. Bei der katalytischen Hydrierung wurden ähnliche Unterschiede festgestellt.

Biocatalytic Redox Reactions for Organic Synthesis: Nonconventional Regeneration Methods
Authors: Hollmann Frank , Arends Isabel W. C. E. , Buehler Katja 
Published: June 2010

AbstractRedox enzymes have tremendous potential as catalysts for preparative organic chemistry. Their usually high selectivity, paired with their catalytic efficiency under mild reaction conditions, makes them potentially very valuable tools for synthesis. The number of interesting monooxygenases, dehydrogenases, reductases, oxidases, and peroxidases is steadily increasing and the tailoring of a given biocatalyst is more and more becoming standard technology. However, their cofactor dependency still represents a major impediment en route to true preparative applicability. Currently, three different approaches to deal with this ‘cofactor challenge’ are being pursued: using whole cells, biomimetic approaches comprising enzymatic cofactor regenerations systems, and ‘unconventional’ nonenzymatic regeneration. The latter technique offers the promise of enabling simple, easily applicable, and robust reaction schemes, for example, by circumventing the ‘cofactor challenge’ and introducing redox power directly to the enzyme’s active sites.
Oxidation Products of Organic Trisulfanes: Molecular Structures and Energies of Various Isomers of the Dimethyltrisulfane Oxides Me2S3O and Me2S3O and of 1,3–tBu2S3O2
Authors: Steudel Ralf , Drozdova Yana 
Published: June 2010

AbstractAb initio MO calculations (MP 2/6–311 G**//HF/6–311 G**) have been performed for several isomers (including rotamers) of Me2S3O and Me2S3O2. MeS(O)SSMe exists as five rotamers; the most stable form (1a) has a helical backbone CSSSC with S‐S bond lengths of 206.0 (SIISII) and 212.4 pm (SIISII). The most stable rotamer of MeS‐S(O)SMe (2a), is less stable than 1a by 10.7 kJ mol‐1; it is of Cs, symmetry, while a rotamer of Cs symmetry (2b) is less stable than 2a by only 1.4 kJ mol‐1. Both 2a and 2b are stabilized by O ⃛ H hydrogen bonds. The S‐S bond lengths of 2a are 210.0 and 212.0 pm; the CSSSC chain is not helical (CSSS torsion angles 166.3 and –75.4°). The 1,3‐dioxide MeS(O)‐SS(O)Me (3) has two equivalent chiral centers and exists as diastereomers. The most stable isomer 3a (RR)/(SS) is of C2 symmetry with methyl groups trans to each other; the SO bonds form an angle of about 90°. The meso form 3b is less stable than 3a by 17.2 kJ mol‐1 and the rotamers 3c and 3d are less stable by 25.6 kJ mol‐1 and 28.4 kJ mol‐1, respectively. The trisulfane‐1.2–dioxide MeS(O)‐S(O)SMe has two nonequivalent chiral centers and exists as five isomers. The most stable form, the (RS)/(SR) form 4a, is less stable than 3a by 21.4 kJ mol‐1 and is characterized by SS bonds of 220.9 (SIIISIII) and 208.3 pm (SIIISII). The rotamer 4b is less stable by 5.9 kJ mol‐1. The isomers 4c, 4d, and 4e are all of (SS)/(RR) configuration and are less stable than 4a by 6.3, 12.7, and 12.0 kJ mol‐1. For comparison, ab initio MO calculations (HF/6–311 G*) for tBuS(O)SS(O)‐tBu yielded two diastereomers of practically identically energy that both contain helical CSSSC backbones. The (RS) form is less stable than the (RR)/(SS) form by 1.8 kJ mol‐1.
Hemoprotein Models Based on a Covalent Helix–Heme–Helix Sandwich: 1. Design, Synthesis, and Characterization

Published: June 2010

AbstractIn this paper we describe the design, synthesis, and spectroscopic characterization of a covalent helix–heme–helix sandwich named FeIII mimochrome I. It contains deuterohemin bound through both propionyl groups to two identical N‐and C‐terminal protected nonapeptides as α‐helical scaffolds. Each peptide moiety bears a His residue in the central position, which acts as axial ligand to the metal ion. The newly developed synthetic strategy is based on a combination of solution and solid‐phase methodologies. It represents a powerful method for obtaining a large variety of analogues containing two symmetric or unsymmetric peptide chains covalently bound to the deuteroporphyrin ring. UV/Visible spectroscopic characterization in buffered 2,2,2‐trifluoroethanol/water solution proves low‐spin bis(his‐tidine) iron(III) coordination; circular dichroism (CD) measurements show an α‐helical conformation for the peptide moieties. Thus, all the data are in agreement with the designed hypothetical model regarding both the iron(III) coordination and the peptide chain structural organization.
The N3 Position of N9‐Substituted Adenine as a Metal Ion Binding Site: Structural and Solution Studies with PdII and PtII Complexes of N6′, N6′,N 9‐Trimethyladenine

Published: June 2010

AbstractSteric blockage of the N1 and N7 sites of 9‐methyladenine for metal complexation is achieved by twofold methylation of the exocyclic amino group. With 6′,6′,9‐trimethyladenine (TrimeA), binding of MII(dien) (M = Pt, Pd) as well as of trans‐[Pt(NH3)2Cl]+ therefore takes place through N 3. X‐ray crystal structure determinations and NMR spectroscopic studies of three compounds are reported, and the effects of PtII and PdII on the geometry and the acid‐base properties of the TrimeA ligand have been measured and compared with those of the free base. TrimeA has a very pronounced self‐stacking tendency in water (K85M−1 according to the isodesmic model of indefinite noncooperative self‐association). Acidity constants derived from potentiometric pH titrations, spectrophotometry, and NMR shift experiments display excellent agreement with each other. Twofold protonated TrimeA, that is H2(TrimeA)2+, carries protons at the N7 and N1 sites; the acidity constants are pKHH2(TrimeA) = – 0.75 and pKHH(TrimeA) = 4.15. These values compare well with those of other adenine residues. Protonation of [Pt(dien)‐(TrimeA‐N3)]2+ occurs at the N7 position, as shown by spectrophotometry and NMR spectroscopy. The acidity constant of the H+ (N7) site in this complex is low, that is pKHH[Pt(dien)(TrimeA)] = 0.3 (as determined by spectrophotometry), but it is not as low as that for the same site when a proton resides at N1 of unmetalated TrimeA. The pKa of the doubly protonated complex, pKHH2[Pt(dien)(TrimeA)], in which the second acidic proton is situated at N1, is about–1.2 ± 0.3. These findings indicate that upon metalation of N3, the sequence of adenine protonation is reversed. While the N7 site still displays basic properties, the N1 site has undergone a dramatic loss in basicity.

Published: June 2010

AbstractWe designed and targeted for synthesis the C‐ring aryl taxoids 2a‐c in order to develop methods for the construction of the taxoid skeleton and to test their cytotoxicity against tumor cells. Compound 2a was synthesized by a convergent route from hydrazone 5 and aldehyde 4. Key steps included a Shapiro reaction to join 5 and 4, a McMurry coupling to construct the 8‐membered ring, a carbonate opening to introduce the 2‐benzoate group, and an allylic oxidation followed by side‐chain attachment. A similar sequence led to compound 2c, whereas attempts to attain 2b were thwarted by the lability of the benzyl group during the carbonate opening. The biological activity of 2a and 2c against tumor cells was considerably less than that of taxol.
Synthesis and Reactions of a Chemical Model of the Urocanase Reaction
Authors: Winter Joachim , Rétey János 
Published: June 2010

AbstractUsing a convergent synthetic strategy starting from nicotinic acid and imidazole, we have prepared the (E) and (Z) isomers of 1‐benzyl‐3‐carbamoyl‐5‐[2‐(ethoxycarbonylmethylene)‐2‐(1‐(p‐to‐lylsulfamoyl)imidazol‐4‐yl)ethyl]pyridinium bromide (21) as models of the urocanase reaction. Domino reactions of both (E)‐21 and (Z)‐21 led to the same spirocyclic compound, (3aRS)‐11‐[9‐([D7]benzyl)‐5‐ethoxy‐1‐(p‐tolylsulfamoyl)‐1H,9H‐furo[2,3‐g]imidazo[5,4‐f]isoquinolyl]carboxamide (33), which was isolated and spectroscopically characterised. A possible sequence of reactions leading to 33 shows a number of analogies to the conversions catalysed by the enzyme urocanase. Removal of the p‐tolylsulfamoyl protecting group of (E)‐21 and (Z)‐21 under mild conditions led to the highly reactive model compounds (E)‐4 and (Z)‐4, which were identified by 1H NMR spectroscopy, but could not be isolated, owing to their instability. To facilitate the monitoring of the reaction cascade by NMR spectroscopy (Z)‐21 was prepared in which the benzyl group was fully deuterated. Its deprotection to (Z)‐4 started a reaction cascade, which led, after purification, to a main product. According to investigations by UV and 1H NMR spectroscopy it seems very likely that 1‐([D7]benzyl)‐3‐carbamoyl‐7‐(ethoxycarbonylmethyl)‐imidazo[4,5‐f]isoquinolinium bromide (27) was formed. The presumed mechanism of its formation again shows similarities with the postulated mechanism of action of urocanase.
A Novel Palladium‐Catalyzed Asymmetric Cyclocarbonylation of Allylic Alcohols to γ‐Butyrolactones
Authors: Yu Wing‐Yiu , Bensimon Corinne , Alper Howard 
Published: June 2010

AbstractA catalyst system based on [Pd2(dba)3]·CHCl3/(‐)‐BPPM has been found to effect asymmetric cyclocarbonylation of certain prochiral allylic alcohols to produce good yields of optically enriched γ‐butyrolactones. The reaction was performed under an atmosphere of H2 (400 psi) and CO (400 psi) at 100°C in methylene chloride for 48 hours. Asymmetric cyclocarbonylation of allylic alcohols with aliphatic substituents proceeded with moderate enantioselectivities (ee = 25–43%). However, enantiomeric excesses of up to 83% were obtained for substrates containing aromatic substituents, in which case the ee was found to be more sensitive to steric, rather than to electronic factors. Recrystallization of the lactones containing an aromatic group from a mixture of CH2Cl2/Et2O/hexanes (0.5/1.0/8.5), by slow evaporation of the solvent or at low temperature, improved the enantiopurities to >98% ee on a reproducible basis. The asymmetric center of the aromatic lactones was assigned the (S)‐configuration based on the X‐ray crystal structure analysis of enantiopure (S)‐(+)‐3,3‐dimethyl‐2‐(2′‐methylphenyl)‐γ‐butyrolactone (2k). A hydridopalladium intermediate is believed to play a key role in this reaction. Enantioselectivity is thought to be brought about by the preferential formation of 6b. The carbon skeleton of 6b fits into the chiral scaffold of (‐)‐BPPM.
Hetero‐Diels–Alder Reaction with Thiazolyl Oxabutadienes—Model Studies Toward the Synthesis of Directly Linked C‐Disaccharide

AbstractA method for the construction of substituted pyranoses by means of the hetero‐Diels–Alder (HDA) reaction of ethyl vinyl ether with 1‐oxabuta‐1,3‐dienes bearing a thiazolyl ring at C‐2 is described. The cycloaddition with 1‐(thiazol‐2‐yl)‐2‐penten‐1‐one (2) occurred with good endo/exo selectivity to give cis‐ and trans‐3,4‐dihydro‐2H‐pyrans 3a and 3b in a ca. 9:1 ratio and 91% overall yield. The elaboration of 3a through the conversion of the thiazole ring into the formyl group and reduction of the latter to alcohol, followed by hydroxylation of the double bond through hydroboration–oxidation led to the ethyl 2,3‐dideoxypyranoside 8. The asymmetric version of this synthetic sequence started from the HDA cycloaddition of the same alkene with the chiral oxabutadiene 10 bearing the D‐galacto‐pentopyranosid‐5‐yl moiety at C‐3. This reaction afforded a mixture of the four diastereomeric cycloadducts—3,4‐dihydro‐2H‐pyrans 11a,b and 12a,b—in 97% overall yield. The reaction was moderately endo and face selective. A high level of endo selectivity (96%) was obtained by the use of catalytic Eu(fod)3. The elaboration of the endo cycloadducts 11a and 12a by the same synthetic sequence as that developed for 3a (i.e. thiazolyl‐to‐formyl conversion and hydroxylation of the double bond) gave the uncommon C‐disaccharides 15 and 16 featuring two directly linked pyranose rings.

AbstractThe design of a new class of chiral [2]catenanes is reported. The self‐assembly of [2]catenanes comprising one or two 3,3′‐bitolyl spacers in the π‐electron‐deficient component, and bis‐p‐phenylene‐34‐crown‐10 (BPP 34 C 10) as the π‐electron‐rich component, is described. The X‐ray crystal structures, together with solution‐state dynamic1H NMR spectroscopic studies, show that the degree of order characterizing the molecular structures is substantially different from that of the “parent” [2]‐catenane, comprising cyclobis(paraquat‐p‐phenylene) and BPP34C10. When appropriately substituted in theirorthopositions, bitolyl compounds can support axial chirality: the self‐assembly of axially chiral [2]catenanes, comprising one or two 3,3′‐disubstituted‐2,2′‐dihydroxy‐1,1′‐binaphthyl spacers, has been achieved in good yields, showing that the introduction of the bulky, axially chiral spacer and the consequent distortion of the cavity of the π‐electron‐deficient component still permits good molecular recognition between the components leading to efficient catenane production. X‐ray crystallography suggests that this recognition is driven by hydrogen bonding and π‐π stacking interactions between the complementary subunits. The hydroxyl groups on the chiral spacer were further functionalized as benzoyl esters in a [2]catenane as well as in the tetracationic cyclophanes; that is, chemistry can be done on these catenanes. The chiral tetracationic cyclophanes exhibit good enantiomeric differentiation toward the D‐ and L‐enantiomers of aromatic amino acids in water and theirN‐acetylated derivatives in organic solvents.
The Nickel‐Catalyzed Carbonylative Cycloaddition of Allyl Halides and Acetylenes: An Efficient Tool for Cyclopentane Annelation

Published: June 2010

AbstractFrom a practical synthetic point of view, the nickel‐mediated carbonylative cycloaddition of alkynes and allyl halides is a straightforward method for obtaining the cyclopentane skeleton in high yields and with controlled stereochemistry, especially when considering the efficiency of the intermolecular version of the reaction. The efforts to make the previously stoichiometric process catalytic in nickel, after experimental mechanistic observations, are reported herein. The unexpected intervention of iron as a reductant and the isolation of a final dimeric species that exhibits interesting tautomeric behavior are also presented. An extension of the reaction to new substrates has led to the conclusion that, although the steric and electronic effects of the alkyne substituents are generally irrelevant in relation to the adducts and their yields, those of the allylic counterpart may have a significant influence on the outcome of the reaction. However, the presence of the amine moiety in the alkyne completely inhibited the reaction. The feasibility of a multicentered reaction was verified with a triacetylene in which up to 12 bonds were created at once and in good yield.
Synthesis of Hierarchical Macro‐/Mesoporous Solid‐Solution Photocatalysts by a Polymerization–Carbonization–Oxidation Route: The Case of Ce0.49Zr0.37Bi0.14O1.93
Authors: Xi Guangcheng , Ye Jinhua 
Published: June 2010

AbstractA hierarchical macro‐/mesoporous Ce0.49Zr0.37Bi0.14O1.93 solid‐solution network has been synthesized on a large scale by means of a simple and general polymerization–carbonization–oxidation synthetic route. The as‐prepared product has been characterized by SEM, XRD, TEM, BET surface area measurement, UV/Vis diffuse‐reflectance spectroscopy, energy‐dispersive X‐ray spectroscopy (EDS), and photoelectrochemistry measurements. The photocatalytic activity of the product has been demonstrated through the photocatalytic degradation of methyl orange. Structural characterization has indicated that the hierarchical macro‐/mesoporous solid‐solution network not only contains numerous macropores, but also possesses an interior mesoporous structure. The mesopore size and BET surface area of the network have been measured as 2–25 nm and 140.5 m2 g−1, respectively. The hierarchical macro‐/mesoporous solid‐solution network with open and accessible pores was found to be well‐preserved after calcination at 800 °C, indicating especially high thermal stability. Due to its high specific surface area, the synergistic effect of the coupling of macropores and mesopores, and its high crystallinity, the Ce0.49Zr0.37Bi0.14O1.93 solid‐solution material shows a strong structure‐induced enhancement of visible‐light harvest and exhibits significantly improved visible‐light photocatalytic activity in the photodegradation of methyl orange compared with those of its other forms, such as mesoporous hollow spheres and bulk particles.

AbstractA cobalt(I)‐mediated convergent and asymmetric total synthesis of angucyclinones with an aromatic B ring has been developed. In the course of our research, we synthesized three naturally occurring anguclinone derivatives, namely, (+)‐rubiginone B2(1), (−)‐8‐O‐methyltetrangomycin (2), and (−)‐tetrangomycin (3). By combining 3‐hydroxybenzoic acid, 3‐methoxybenzoic acid, citronellal, and geraniol as starting materials in a convergent way, we were able to synthesize chiral triyne chains, which were cyclized with [CpCo(C2H4)2] (Cp=cyclopentadienyl) by means of an intramolecular [2+2+2] cycloaddition to their corresponding tetrahydrobenzo[a]anthracenes. Successive oxidation and deprotection steps led to the above‐mentioned natural products1–3.
