Abstract

Preparation of both the enantiomers of 4-hydroxy-2,6,6-trimethyl-2- cyclohexen-1-one (phorenol), which are versatile synthetic intermediates for abscisic acid and carotenoids, was achieved by hydrolase-catalyzed hydrolysis of the corresponding chloroacetate. The hydrolysis with esterase SNSM-87 (Nagase) enriched the (S)-ester, while lipase P (Amano) afforded the (R)- ester.
