标 题 :Stereoselective synthesis of 2-hydroxy-4-phenylbutyric acid esters
发明人：TIKARE RAVEENDRA KHANDURAO
权利人:FERMENTA BIOTECH LTD
摘要:A process is described for the stereospecific preparation of an ester of formula (I): wherein * signifies the (R) stereoisomer; R 1 is selected from C 1-6 alkyl, preferably ethyl; and R 2 is hydrogen, a protecting group or a leaving group which process comprises reaction of a nitrile of formula (II): wherein * signifies the (R) stereoisonomer; and Ph is the phenyl group C 6 H 5 with a solution of an inorganic acid in an alcohol and optional conversion of the compound of formula (I) wherein R 2 is H so prepared to any other desired compound of formula (I) by standard methods in the art. The compounds of formula (I) are chiral esters, useful as intermediates in the synthesis of the family of acetylcholine esterase (ACE) inhibitors known as “prilsâ€?, such as lisinopril, cilazapril, enalapril, benazepril, ramipril, delapril, enalaprilat, imidapril, spirapril, trandolapril and others.n n*n nPh-CH 2 —CH 2 —CH(OR 2 )—COOR 1   (I)n n*n nPh-CH 2 —CH 2 —CH(H)—CN  (II)

摘要:The present invention provides a process for the preparation of racemic or chiral octahydro-6-(phenylmethyl)-1H-pyrrolo[3,4-b]pyridine of formula I, a key intermediate in the synthesis of moxifloxacin or its pharmaceutically acceptable salts. The process comprises reaction of racemic or chiral tetrahydro-6-(phenylmethyl)-1H- pyrrolo[3,4-b]pyridine-5,7(6H)-dione of formula II with a reducing agent, which is a mixture of two agents, that is mixture of dimethyl sulphate and sodium borohydride or aluminum chloride and sodium borohydride used in a molar ratio ranging from 1:1 to 1: 4, in the presence of a polar solvent at a temperature ranging from 15°C to 45°C 10 to obtain racemic or chiral octahydro-6-(phenylmethyl)-1H-pyrrolo[3,4-b]pyridine of formula I having purity ≥ 96%.
