| titleOfInvention | Preparation of optically active ester |
| abstract | PURPOSE:To prepare an optically active ester useful as an insecticidal component, in high optical purity, economically in an industrial scale, by using a microbial asymmetric hydrolysis, etc. CONSTITUTION:The ester of formula IV (A is H, alkyl, etc.) is subjected to the asymmetric hydrolysis with an esterase produced by a microorganism belonging to Arthrobacter genus and capable of asymmetrically hydrolyzing said ester to obtain a mixture of an optically active alcohol of formula III (* is asymmetric carbon atom) and the ester of the antipode of said alcohol. The mixture is made to react with the carboxylic acid halide of formula II (R is substituted cyclopropyl, substituted benzyl, etc.) in the presence of an acid acceptor to acylate the optically active alcohol of formula III, and the optically active ester of formula I (R and * are same as defined above) is separated from the resultant reaction mixture. |
