OPTICALLY ACTIVE EPOXYPROPIONIC ACID ESTER DERIVATIVE, ITS INTERMEDIATE AND METHOD FOR PRODUCING THEREOF

摘要

PROBLEM TO BE SOLVED: To obtain an optically active epoxypropionic acid ester derivative useful as a synthetic intermediate of medicinal agents and agrochemicals and its intermediate and provide a method for producing thereof. SOLUTION: This optically active epoxypropionic acid ester derivative is obtained by epoxidizing a 1-phenyl-4,4-dimethyl-1-pentene-3-one in the presence of an asymmetric catalyst and subsequently oxidizing the epoxidized product.
