Title:
PROCESS FOR PRODUCING OPTICALLY ACTIVE THEASPIRANE
Document Type and Number:
WIPO Patent Application WO/2007/032279
Kind Code:
A1
Abstract:
A process for easily producing a stereoisomer of theaspirane having a high optical purity. 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 theaspirane having a desired configuration and having a high optical purity is obtained in a satisfactory yield.
