Description:
FIELD OF THE INVENTION  
         [0001]    The invention relates to a hitherto unknown class of compounds, namely substituted 1,3,2 oxazaphosphacycloalkane derivatives, which exhibit matrix metalloprotease inhibitory effects, to pharmaceutical compositions comprising said compounds and to the use of said compounds in the manufacture of medicaments.  
         BACKGROUND OF THE INVENTION  
         [0002]    The matrix metalloproteases (MMP) are a family of zinc containing enzymes capable of breaking down many protenaceous compounds in the extracellular matrix, such as collagen, gelatine, fibronectin, laminin and proteoglucan core protein.  
           [0003]    There are at least 23 different MMPs classified according to their domain structure and substrate preferences [Lauer-Fields,  Exp.Opin.Ther.Patents,  10, 1873-1884, 2000]. MMP may be classified into four main groups: Collagenases degrade fibrilar collagen; stromelysin degrade proteoglucans and glucoproteins; gelatinases degrade non-fibrilar and degraded collagen, i.e. gelatine; and finally the membrane bound MMPs [O&#39;Brien,  J.Med.Chem., 43, 156-166, 2000]. The MMPs share a common multidomain structure, but are glycosylated at different sites and to different extent. All MMPs also share a common zinc-binding motif, HisGluXaaGlyHis, and the differences comprise the presence or absence of structural domains controlling such factors as substrate specificity, inhibitor binding, matrix binding and cell-surface localisation. The nomenclature for MMP is simple as they are named MMP-n, wherein n is an integer starting from 1.  
           [0004]    MMP plays an important physiological role in tissue remodelling in normal tissue, e.g. angiogenesis, wound healing, bone resorption, ovulation and embryonic development. In healthy tissue, the activity of MMP is carefully controlled by gene expression, by synthesis of the enzymes in a latent pro-enzyme form, and by co-expression of endogenous tissue inhibitors of MMP (TIMP). Excessive or poorly regulated MMP activity has been implicated in a host of pathological conditions, and there has thus been a large effort to design drugs with MMP inhibitor effects, which could be used to re-establish control of the MMP activity.  
           [0005]    Many known MMP inhibitors are peptide derivatives, based on naturally occurring amino acids, and with structural similarities to the cleavage sites in the natural substrates of MMP. Other known MMP inhibitors have less peptidic structure, and may be classified as pseudopeptides or peptidomimetics, e.g. sulfonamides.  
           [0006]    Prior art of MMP inhibitors consists of peptidic structures [WO 95/19965 and WO 95/19956]; linear and cyclic sulfonamide compounds, [WO 97/44315, WO 00/09485 and EP 0979 816] and buturic and pentanoic acid derivatives [WO 97/43237, WO 97/43239 and WO 99/61413].

           [0150]    The compounds of the present invention can be prepared in a number of ways well known to those skilled in the art of organic synthesis. The compounds of the present invention can be synthesised using the methods outlined below, together with methods known in the art of synthetic organic chemistry, or variations thereof as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below.  
           [0151]    The novel compounds of formula (I) may be prepared using the reactions and techniques described in this section. The reactions are performed in solvents appropriate to the reagents and materials employed and suitable for the transformations being effected. Also, in the synthetic methods described below, it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of experiment and work-up procedures, are chosen to be conditions of standard for that reaction, which should be readily recognised by one skilled in the art. It is understood by one skilled in the art of organic synthesis that the functionality present on various portions of the educt molecule must be compatible with the reagents and reactions proposed. Not all compounds of formula (I) falling into a given class may be compatible with some of the reaction conditions required in some of the methods described. Such restrictions to the substituents which are compatible with the reaction conditions will be readily apparent to one skilled in the art and alternative methods can be used.  
           [0152]    Compounds according to the present invention in which X is a hydroxamic acid group —CONHOH may be prepared from compounds of the invention in which X is a carboxylic acid group —COOH. That process comprises reacting an acid of general formula (II) (in these and the following formulae R1, R2, R3, R4 , R10, R11 and n have the above meanings unless otherwise specifically indicated; R13 represents an alkyl)  
                         
 
           [0153]    with hydroxylamine, O-protected hydroxylamine or N,O-diprotected hydroxylamine. Other substituents of the acids (II) may themselves be protected from such reaction, and the protecting groups may subsequently be removed from the resulting hydroxamic acid moiety.  
           [0154]    The condensation is carried out using one of the many methods for the formation of amide bonds known to one skilled in the art of organic synthesis, e.g. the mixed carbonic anhydride (isobutyl chloroformate) method.  
           [0155]    Compounds according to the present invention in which X is a hydroxamic acid group —CONHOH may also be prepared from esters of general formula (III). That process comprises reacting an ester of general formula (III) with hydroxylamine or O-protected hydroxylamine in the presence of a base.  
                         
 
           [0156]    Compounds according to the present invention in which X is a carboxylic acid group —COOH may be prepared from esters of general formula (III) by basic hydrolysis.  
                         
 
           [0157]    The esters of formula (III) may be prepared from phosphonyl dichlorides (IV) and amino alcohols (V) in the presence of a base.  
                         
 
           [0158]    The esters of formula (III) may also be prepared from phosphonyl dichlorides (IV) and amino alcohols (VI) in the presence of a base and subsequent alkylation of the intermediate oxazaphosphacycloalkane (VII) utilising haloesters (VIII) in the presence of a base.  
                         
 
           [0159]    Starting materials (IV) are either commercially available or readily prepared from aryl bromides or aryl triflates by palladium catalysed phosphonation (Hirao et al., Synthesis, 56-57, 1981) followed by chlorination (H. Quast et al., Synthesis, 490, 1974 or N. N. Bhongle et al., Synthetic Communications, 17, 1071-76 (1987)).  
           [0160]    Starting materials (V) are readily obtained e.g. by alkylation of aminoalkohols (VI) with haloesters (VIII). Aminoalcohols (V) in which R3 and R4 are hydrogen and in which n=1 or 2 may be prepared from homoallylic amino acid esters (J. Org. Chem., 59, 7766-7773 (1994)) by ozonolysis/reduction (n=1) or hydroboration/oxidation (n=2).  
                         
 
           [0161]    Starting materials (VI), in which R4 is hydrogen may be prepared using routine synthetic methods for instance in the following manner: Nitrones of general formula (IX) (prepared as described in Synth. Comm. 24(18), 2537-2550 (1994) or Synlett (5), 602-604 (1999)) may be heated in ω-alkenyl alcohols to give the isoxazolidines (X), which may subsequently be reduced by treatment with Zn-dust in acetic acid at 60° C. to yield aminodiols (XI). The primary alcohol may be protected using triisopropylsilylchloride and base, the amino-function may be protected using ditertbutyl-dicarbonate to yield compounds (XII). The secondary alcohol may then either be protected using e.g. acetic anhydride and base or alkylated using an alkylhalide and base, the benzyl group may be removed using 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and the BOC and silyl-protecting groups may simultaneously be removed using HCl in ethanol at 60° C. to give compounds (VI), in which PG denotes either alkyl group or a protecting group to be removed at a later stage.  
                         
 
           [0162]    Starting materials (VI) in which R4 is an hydroxy-group and R10, R11 and R3 are hydrogen are commercially available.  
           [0163]    Starting materials (VI), in which R3 and R4 are hydrogen are either commercially available, known compounds or may be prepared using routine synthetic methods for instance in the following manner:  
                         
 
           [0164]    nitrones (IX) (prepared as described in Synlett (5), 602-604 (1999)) may be condensed with silylated alkynols (XX) in the presence of lithium diisopropylamine (LDA) at −70° C. The resulting hydroxylamines (XIII) may then be treated with Zn-dust in acetic acid/methanol to yield amines (XIV). Subsequent hydrogenation and treatment with HCl in ethanol may then afford amines (VI).  
           [0165]    Alternatively, starting materials (VI) in which R3 and R4 are hydrogen with n=1 or 2 may be prepared from substituted 4-amino-1-butenes (J. Org. Chem., 59, 7766-7773, 1994) by standard ozonlysis/reduction (n=1) or by hydroboration/oxidation (n=2), with the amino group appropriately protected.  
           [0166]    Starting materials (VI) in which R3 and R4 are hydroxy or alkoxy may be prepared from compounds (XIV) by dihydroxylation. The resulting alcohol functions may, if necessary, be alkylated using an alkylhalide and base after BOC protection of the amino group, and the benzyl, silyl and BOC protecting groups subsequently be removed as described for compounds (XIV).  
           [0167]    Starting materials (VI) in which R4 is hydrogen may be prepared from compounds (XIV) by hydroboration/oxidation or by epoxidation followed by ring-opening of the epoxide using e.g. Red-Al. The resulting alcohol function may, if necessary, be alkylated using an alkylhalide and base after BOC protection of the amino group, and the benzyl, silyl and BOC protecting groups subsequently be removed as described for compounds (XIV).  
           [0168]    Starting materials (VI) in which R4 is hydroxy or alkoxy, R3 is hydrogen and n=1 may be prepared from 4-benzyloxycarbonylamino-3-hydroxybutyric acid (XXI, Tetrahedron 50(47), 13347-68 (1994)) in the following manner:  
                         
 
           [0169]    R14 represents an alkyl or a transient protecting group, such as a silyl group. Alkylation or silylation is carried out by standard synthetic methods. If R14 is a silyl, this group is cleaved after cyclisation of (VI) with a phosphonyl dichloride (IV).  
           [0170]    Starting materials (VIII) containing bromine are either commercially available or easily prepared from the corresponding amino acids by standard synthetic methods (e.g. J.Org.Chem. 50(9), 1356-1359 (1985)) and subsequent esterification. Starting materials (VIII) containing iodine can be prepared by conversion of the bromoacetic acid esters (VIII) with sodium iodide.  
           [0171]    Compounds (XVI) according to the present invention in which X is a phosphonic acid group —P(O)(OH)2 may be prepared by alkylation of oxazaphosphacycloalkanes (VII) with alkyl or silyl phosphonate halides (XV), in the presence of base, followed by deprotection. The deprotection of alkyl phosphonates is carried out by treatment with TMSI. Silyl phosphonates are readily converted to phosphonic acids by treatment with water. Alkyl phosphonate halides (XV) are commercially available or known compounds.  
                         
 
           [0172]    Compounds (XVIII) according to the present invention in which X is an acetylthiomethyl moiety —CH 2 SCOCH 3  may be prepared by alkylation of oxazaphosphacycloalkanes (VII) with an acetylthioethyl halide (XVII) in the presence of base. Compounds (XIX) according to the present invention in which X is a mercaptomethyl —CH2SH group may prepared by removal of the acetyl group from compounds (XVIII) with aqueous base  
                         
 
           [0173]    Preparation of pure isomeric compounds of the invention may be accomplished in one of the following ways:  
           [0174]    1. Preparation of enantiomerically pure intermediates (V) or (VI) by enantioselective syntheses as described in J. Org. Chem. 59, 7766-7773, 1994. Furthermore, a few optically active amino alcohols VI are commercially available. Subsequent ring closure with phosphonyl dichlorides (IV) affords a pair of diastereoisomers that may be separated by chromatography.  
           [0175]    2. Optical resolution of the racemic oxazacyclophosphane intermediates (VII) using chiral silyl chlorides according to the procedure described in J. Org. Chem. 43, 1111-1114 (1978).  
           [0176]    3. Esterification of racemic carboxylic acid intermediates (II) with optically active alcohols such as (−)-menthol or (−)-N-methylephedrine, or amidation with optically active amines such as (−)-2-phenylglycinol or Evans&#39; oxazolidinones. The resulting diastereoisomeric esters or amides may be separated by either crystallisation or by chromatography and hydrolysed to afford optically active carboxylic acids.  
           [0177]    4. Resolution of diastereomeric salts formed from the racemic carboxylic acids (II) and optically active bases such as quinotoxine or cinchotoxine.  
           [0178]    5. Resolution of the racemic oxazacyclophosphanes (VII) or esters (III) by chiral chromatography.  
           [0179]    After the preparation of pure isomeric intermediates by any of the above methods, the intermediates may be transformed to compounds of formula I by the reactions described herein.  
           [0180]    Imbalance in MMP production or activity has been implicated in many diseases, hence the therapeutic value of MMP inhibitors. Compounds that have the property of inhibiting MMP are thus believed to be potentially useful for treating, preventing and/or ameliorating disease severity, disease symptoms, and/or periodicity of reoccurrence of a disease or condition associated with an imbalance in MMP production or activity. Diseases or conditions include those involving tissue breakdown or inflammation, such as rheumatoid arthritis, osteoarthritis, osteopenias, such as osteroporosis, periodontitis, gingivitis, corneal epidermal, gastric ulceration, skin ageing, tumour metastasis, tumour invasion and tumour growth; diseases associated with neuroinflammatory disorder, including those involving myelin degradation, such as multiple sclerosis; angiogenesis dependent diseases, which include arthritic conditions and solid tumour growth, psoriasis, proliferative retinopathies, neovascular glaucoma, ocular tumours, angiofibromas and hemangiomas [Vu in  Metalloproteases,  Parks and Mecham (Eds.), 115-148, 1998, Academic Press; Mullins,  Biochem.Biophys.Acta,  695, 117-214, 1983; Henderson,  Drugs of the Future,  15, 495-508, 1990; Reich,  Cancer Res,  48, 3307-3312, 1988; Whitaker,  Chem.Rev.,  99, 2735-2776, 1999].  
           [0181]    Moreover, MMP inhibitors are also potentially useful for treating, preventing and/or ameliorating disease severity, disease symptoms, and/or periodicity of reoccurrence of a disease or condition associated excess Tumour Necrosis Factor α (TNF-α) production [Whitaker,  Chem.Rev.,  99, 2735-2776, 1999]. TNF-α is a potent proinflammatory cytokine which has been implicated in inflammatory diseases or conditions, arthritis, asthma, septic shock, fever, cardiovascular effects, haemorrage, coagulation, acute phase reponse, Crohn&#39;s disease, mycobacterial infection, meningitis, psoriasis, congestive heart failure and apoptosis. TNF-α is expressed in the cells as a membrane-bound 26 kDa protein, which is proteolytically cleaved to release a 17 kDa active, soluble form. The TNF-α processing is catalysed by the enzyme TNF-α convertase (TACE), which is a metalloprotease, and several MMP inhibitors have been found to inhibit TNF-α processing [Mohler,  Nature,  370, 218, 1994]. Excess TNF-α production can thus potentially be controlled by treatment with an MMP inhibitor.  
           [0182]    In another aspect, the invention relates to pharmaceutical formulations of a compound of formula I. The formulations of the present invention, both for veterinary and for human medical use, comprise active ingredients in association with a pharmaceutically acceptable carrier(s) and optionally other therapeutic ingredient(s). The carrier(s) must be “acceptable” in the sense of being compatible with the other ingredients of the formulations and not deleterious to the recipient thereof.  
           [0183]    Conveniently, the active ingredient comprises from 0.1-100% by weight of the formulation. Conveniently, dosage unit of a formulation contain between 0.07 mg and 1 g of a compound of formula I.  
           [0184]    By the term “dosage unit” is meant a unitary, i.e. a single dose which is capable of being administered to a patient, and which may be readily handled and packed, remaining as a physically and chemically stable unit dose comprising either the active material as such or a mixture of it with solid or liquid pharmaceutical diluents or carriers.  
           [0185]    The formulations include e.g. those in a form suitable for oral (including sustained or timed release), rectal, parenteral (including subcutaneous, intraperitoneal, intramuscular, intraarticular and intravenous), transdermal, ophthalmic, topical, nasal or buccal administration.  
           [0186]    The formulations may conveniently be presented in dosage unit form and may be prepared by any of the methods well known in the art of pharmacy, e.g as disclosed in Remington,  The Science and Practice of Pharmacy,  20 th  ed., 2000. All methods include the step of bringing the active ingredient into association with the carrier, which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing the active ingredient into association with a liquid carrier or a finely divided solid carrier or both, and then, if necessary, shaping the product into the desired formulation.  
           [0187]    Formulations of the present invention suitable for oral administration may be in the form of discrete units as capsules, sachets, tablets or lozenges, each containing a predetermined amount of the active ingredient; in the form of a powder or granules; in the form of a solution or a suspension in an aqueous liquid or non-aqueous liquid, such as ethanol or glycerol; or in the form of an oil-in-water emulsion or a water-in-oil emulsion. Such oils may be edible oils, such as e.g. cottonseed oil, sesame oil, coconut oil or peanut oil. Suitable dispersing or suspending agents for aqueous suspensions include synthetic or natural gums such as tragacanth, alginate, acacia, dextran, sodium carboxymethylcellulose, gelatin, methylcellulose, hydroxypropylmethylcellulose, hydroxypropylcellulose, carbomers and polyvinylpyrrolidone. The active ingredients may also be administered in the form of a bolus, electuary or paste.  
           [0188]    A tablet may be made by compressing or moulding the active ingredient optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing, in a suitable machine, the active ingredient(s) in a free-flowing form such as a powder or granules, optionally mixed by a binder, such as e.g. lactose, glucose, starch, gelatine, acacia gum, tragacanth gum, sodium alginate, carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, polyethylene glycol, waxes or the like; a lubricant such as e.g. sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride or the like; a disintegrating agent such as e.g. starch, methylcellulose, agar, bentonite, croscarmellose sodium, sodium starch glycollate, crospovidone or the like or a dispersing agent, such as polysorbate 80. Moulded tablets may be made by moulding, in a suitable machine, a mixture of the powdered active ingredient and suitable carrier moistened with an inert liquid diluent.  
           [0189]    Formulations for rectal administration may be may in the form of suppositories in which the compound of the present invention is admixed with low melting water soluble or insoluble solids such as cocoa butter, hydrogenated vegetable oils, polyethylene glycol or fatty acids esters of polyethylene glycols, while elixirs may be prepared using myristyl palmitate.  
           [0190]    Formulations suitable for parenteral administration conveniently comprise a sterile oily or aqueous preparation of the active ingredients, which is preferably isotonic with the blood of the recipient, e.g. isotonic saline, isotonic glucose solution or buffer solution. The formulation may be conveniently sterilised by for instance filtration through a bacteria retaining filter, addition of sterilising agent to the formulation, irradiation of the formulation or heating of the formulation. Liposomal formulations as disclosed in e.g. Encyclopedia of Pharmaceutical Tehcnology, vol.9, 1994, are also suitable for parenteral administration.  
           [0191]    Alternatively, the compound of formula I may be presented as a sterile, solid preparation, e.g. a freeze-dried powder, which is readily dissolved in a sterile solvent immediately prior to use.  
           [0192]    Transdermal formulations may be in the form of a plaster or a patch.  
           [0193]    Formulations suitable ophthalmic administration may be in the form of a sterile aqueous preparation of the active ingredients, which may be in microcrystalline form, for example, in the form of an aqueous microcrystalline suspension. Liposomal formulations or biodegradable polymer systems e.g. as disclosed in Encyclopedia of Pharmaceutical Tehcnology, vol.2, 1989, may also be used to present the active ingredient for ophthalmic administration.  
           [0194]    Formulations suitable for topical or ophthalmic administration include liquid or semi-liquid preparations such as liniments, lotions, gels, applicants, oil-in-water or water-in-oil emulsions such as creams, ointments or pastes; or solutions or suspensions such as drops.  
           [0195]    Formulations suitable for nasal or buccal administration include powder, self-propelling and spray formulations, such as aerosols and atomisers.  
           [0196]    Prodrugs of the present invention may also be delivered by use of monoclonale antibodies as individual carriers to which the compound molecules are coupled.  
           [0197]    In addition to the aforementioned ingredients, the formulations of a compound of formula I may include one or more additional ingredients such as diluents, buffers, flavouring agents, colourant, surface active agents, thickeners, preservatives, e.g. methyl hydroxybenzoate (including anti-oxidants), emulsifying agents and the like.  
           [0198]    In the systemic treatment using the present invention daily doses of from 0.001-500 mg per kilogram body weight, preferably from 0.002-100 mg/kg of mammal body weight, for example 0.003-20 mg/kg of a compound of formula I is administered, typically corresponding to a daily dose for an adult human of from 0.01 to 37000 mg. In the topical treatment of dermatological disorders, ointments, creams or lotions containing from 0.1-750 mg/g, and preferably from 0.1-500 mg/g, for example 0.1-200 mg/g of a compound of formula I is administered. For topical use in ophthalmology ointments, drops or gels containing from 0.1-750 mg/g, and preferably from 0.1-500 mg/g, for example 0.1-200 mg/g of a compound of formula I is administered. The oral compositions are formulated, preferably as tablets, capsules, or drops, containing from 0.07-1000 mg, preferably from 0.1-500 mg, of a compound of formula I per dosage unit.  
           [0199]    The invention also includes incorporating other pharmacologically active ingredients, normally used in the treatment of the disease states mentioned above, into the formulation of the present invention. Such active ingredients may be anti-cancer drugs, such as chemotherapeutic agents, hormonal agents or biological response modifiers.  
           [0200]    Administration to patients in need thereof of the compounds or compositions of the present invention is expected to be useful in the treatment of the above mentioned diseases.

       General Procedure 1: Formation of Hydroxamic Acids of General Formula (Ia) from the Corresponding Carboxylic Acids of General Formula (II)  
       [0221]    A solution of carboxylic acid with general formula (II) (2.9 mmol) in THF (45 ml) was cooled to −10° C. under argon. NMM (0.3 ml, 3.0 mmol) and isobutyl chloroformate (0.4 ml, 3.0 mmol) were then added with stirring. After stirring overnight at −10° C., O-trimethylsilyl hydroxylamine (0.4 ml, 3.2 mmol) was added, and the mixture was left at −10° C. for 5 h. The mixture was then acidified with 4 M acetic acid, extracted with EtOAc/H 2 O. The aqueous layer was back-extracted with EtOAc, and the combined organic layers were washed with brine, dried (MgSO 4 ) and concentrated. The residue was purified by chromatography (chloroform/methanol/NH 3  (25%)) or crystallisation to afford the hydroxamic acid of general formula (Ia).  
       General Procedure 2: Formation of Hydroxamic Acids of General Formula (Ia) from the Corresponding Esters of General Formula (III)  
       [0222]    To a solution of ester with general formula (III) (0.20 mmol) in dry methanol (2 ml) was added O-trimethylsilyl-hydroxylamine (72 μl, 0.60 mmol) and sodium methoxide (1.4 M, 214 μl, 0.30 mmol). After stirring at rt for 5 hours, the solution was acidified with 4 M AcOH to pH 4, concentrated under reduced pressure and extracted with EtOAc/H 2 O. The aqueous layer was back-extracted with EtOAc, and the combined organic layers were washed with brine, dried (MgSO 4 ) and concentrated under reduced pressure. The residue was purified by chromatography (chloroform/methanol/NH 3  (25% aq.)) or crystallisation to afford the hydroxamic acid of general formula (Ia).  
       General Procedure 3: Formation of Carboxylic Acids of General Formula (II) from the Corresponding Oxazaphosphacycloalkane Esters of General Formula (III)  
       [0223]    A solution of ester with general formula (III) (0.26 mmol) in methanol (2 ml) and aqueous sodium hydroxide (2 M, 2 ml) was stirred overnight at rt, acidified with 4 M AcOH and extracted with EtOAc/H 2 O. The aqueous phase was back-extracted with EtOAc, and the combined layers were washed with brine, dried (MgSO 4 ) and concentrated under reduced pressure. The residue was purified by chromatography (chloroform/methanol/acetic acid) or by crystallisation to afford the carboxylic acid of general formula (II).  
       General Procedure 4: Formation of Oxazaphosphacycloalkane Esters of General Formula (III) by Cyclisation of Phosphonyldichlorides of General Formula (IV) with Amino Alcohols of General Formula (V)  
       [0224]    A solution of amino alcohol of general formula (V) (0.42 mmol) and NMM (0.85 mmol) in dry CH 2 Cl 2  (20 ml) was cooled to −40° C. under argon, and a solution phosphonyldichloride of general formula (IV) (0.42 mmol) in dry CH 2 Cl 2  (10 ml) was added. The mixture was stirred at 0° C. for 1 hour, then at rt overnight. After quenching with water, the aqueous phase was extracted with EtOAc. The aqueous phase was back-extracted with EtOAc. The combined organic layers were washed with brine, dried (MgSO 4 ) and concentrated under reduced pressure. The residue was purified by chromatography (chloroform/methanol) to afford the oxazaphosphacycloalkane ester of general formula (III).  
       General Procedure 5.  
       [0225]    Formation of Oxazaphosphacycloalkanes of General Formula (VII) by Cyclisation of Phosphonyldichlorides of General Formula (IV) with Amino Alcohols of General Formula (VI)  
         [0226]    A solution of amino alcohol of general formula (VI) (1.0 mmol) and triethylamine (2.2 mmol) in dry CH 2 Cl 2  (25 ml) was cooled 0° C. under argon, and a solution phosphonyidichloride of general formula (IV) (1.1 mmol) in dry CH 2 Cl 2  (2 ml) was added. The mixture was stirred at 0° C. for 1 hour, then at rt overnight. After quenching with water, the aqueous phase was extracted with EtOAc. The aqueous phase was back-extracted thoroughly with EtOAc.

       [0227]    Formation of Oxazaphosphacycloalkane Esters of General Formula (III) by Alkylation of Oxazaphosphacycloalkanes of General Formula (VII) with Bromo- or Iodoacetic Acid Esters of General Formula (VIII)  
         [0228]    A solution of oxazaphosphacycloalkane of general formula (VII) (0.76 mmol) in dry THF (4 ml) was cooled to −70° C., and n-butyllithium (0.76 mmol) was added dropwise. The mixture was stirred at −70° C. for 2 hours, followed by a addition of a solution of bromo- or iodoacetic acid ester of general formula (VIII) (1.52 mmol) in dry THF (1.5 ml). The mixture was removed from the cooling bath and stirred at rt for overnight, quenched with water and extracted with EtOAc/H 2 O. The aqueous phase was back-extracted thoroughly with EtOAc, and the combined organic layers were washed with water and brine, dried (MgSO 4 ) and concentrated under reduced pressure. The residue was purified by chromatography to afford the oxazaphosphacycloalkane ester of general formula (III).
