OPTICALLY ACTIVE EPOXYCYCLOHEXANE DERIVATIVE, OPTICALLY ACTIVE EPOXYCYCLOHEXANONE DERIVATIVE, AND PRODUCTION OF SAID DERIVATIVES

摘要

An optically active epoxycyclohexane derivative of general formula (I); and its enantiomers wherein R represents 4-oxycarbonyl-1-hydroxy-3-methyl-3(Z)-buten-1-yl or 4-hydroxycarbonyl-3-methyl-1(E), 3(Z)-butadien-1-yl; and R?1 and R2¿ each represent lower alkoxy or R1, R2 and a carbon atom bonded thereto form together a 1,3-dioxolane ring. An optically active epoxycyclohexanone derivative of general formula (II); and its enantiomers wherein R3 represents hydrogen, lower alkyl, allyl, aralkyl or aryl.
