Abstract
A simplified production method of stereoisomer of theaspiran having high optical purity has been desired. An alcohol compound having a specific skeleton is enantioselectively esterified with an enzyme, or an ester compound having a specific skeleton is enantioselectively hydrolyzed with an enzyme. The resultant optically active ester or optically active alcohol is used. Thus, optically active theaspiran having a desired configuration and having a high optical purity is obtained in a satisfactory yield.
