    Abstract: PCT No. PCT/EP96/03948 Sec. 371 Date Jan. 27, 1998 Sec. 102(e) Date Jan. 27, 1998 PCT Filed Sep. 9, 1996 PCT Pub. No. WO97/10201 PCT Pub. Date Mar. 20, 1997The present invention relates to a process for cleaving optically active amides to carboxylic acids and optically active amines with retention of the center of chirality, wherein the amides are hydrolyzed in the presence of a polyol or of an amino alcohol and of an alkali metal or alkaline earth metal hydroxide.

Date Mar. 30, 1995A process for producing optically active primary and secondary amines from the corresponding racemates is characterised in that (a) a racemic amine is enantioselectively acylated in the presence of a hydrolase with an ester whose acid component bears a fluorine, nitrogen, oxygen or sulphur atom at the proximity of the carbonyl carbon atom; (b) the mixture of optically active amine and optically active acylated amine is separated so that an enantiomer of amine is produced; (c) if desired the other enantiomer of the amine is extracted from the acylated amine by amide cleavage.

Date Mar. 2, 1995A process for the preparation of (L)-2-chloropropionic acid and its alkali metal, alkaline earth metal or ammonium salts which comprises hydrolyzing isobutyl L-chloropropionate at a pH of from 4 to 8 in the presence of a lipase from Pseudomonas spec. DSM 8246 and isolating the optically active reaction product from the reaction mixture either directly or after conversion of the salt into the acid in a conventional way, or further reacting it in situ. The optically active products are important intermediates for preparing crop protection agents.\!
