Abstract

PURPOSE: To obtain an optically active propionic acid by the reaction of a new derivative of 6-substituted-methylidene-5, 7-dioxo-perhydro-1, 4-oxazepin with Grignard reagent, followed by the hydrolysis.
CONSTITUTION: An optically active derivative of propionic acid of forjula II having the asymmetric center at β-position, by the reaction of a stereo isomer (new material) of 6-substituted-methylidene-5, 7-dioxo-perhydro-1, 4-oxazepin derivative of formula I (R1 and R2 are alkyl, or together form a 5- or 6-membered ring; R3=H or aryl; R4=lower alkyl, cycloalkyl, etc.) with Grignard reagent, followed by the hydrolysis.
EFFECT: The reaction in the presence of a metal halide gives the objective compound with high optical purity in high yield.
USE: Pharmaceutical, e.g. antiinflamatory agnets, antidiabetics, or their intermediates
