| abstract | PURPOSE: To efficiently obtain useful agricultural chemical in high yield by reacting a specific compound with a hydrolytic enzyme or enzyme mixture containing one or more kind of hydrolytic enzymes. n CONSTITUTION: A microorganism of the genus Candida such as Candida cylindracea strain is cultured to afford an asymmetric hydrolytic enzyme (A) such as lipase OF. Then methyl 2-substituted-2-benzyloxy-2-methyl-carboxylate (C) expressed by formula I (R is 2-12C saturated or unsaturated alkyl) and the above-mentioned enzyme A are added to a phosphoric acid buffer of pH5-8 to give the reaction mixture liquid (D). Then the ingredient D is subjected to reciprocating shaking reaction at about 30°C for 2-3 day to provide a reaction product (E). Then the ingredient E is controlled to about pH9 and extracted and purified with diethyl ether, etc., to provide an optically active ester expressed by formula II (asteric C is optically active carbon) and/or optically active carboxylic acid expressed by formula III in an optical resolution method. n COPYRIGHT: (C)1991,JPO&Japio |
