Abstract
An optically active alcohol of this invention is obtained from a process using an enzyme having the ability to conduct preferentially a transesterification reaction with a triglyceride and an (R,S)-alcohol represented by a general formula: ##STR1## wherein X indicates alkyl group having a carbon number of 2-10, Y indicates alkyl group having a carbon number of 1-3, CF.sub.3 or CN, and X.noteq.Y. In this process, the (R,S)-alcohol of the above formula (1) and the triglyceride are reacted under substantially anhydrous conditions. The obtained ester is resolved and the optically active alcohol which contains richly either R- or S-alcohol is produced the optically active alcohol is efficiently obtained by an industrially advantageous biochemical method.
