PROCESS FOR PRODUCTION OF OPTICALLY ACTIVE 3-HYDROXY- PENTANENITRILE

摘要

A process for producing optically active 3−hydroxy− pentanenitrile in a high yield by reducing 3−ketopentanenitrile stereoselectively by the use of an enzyme capable of reducing 3−ketopentanenitrile asymmetrically into optically active 3−hydroxypentanenitrile. 3−Ketopentanenitrile alkali metal salts can be also obtained efficiently, which are stable compounds unproblematic in respect of storage.
