Abstract

The reaction of α-methylbenzylamine with dimethyl meso and racemic dibromosuccinate resulted in the formation of trans-aziridine(Ib) and Schiff base(III) of dimethyl oxaloacetate. The optically active III was hydrogenated and hydrogenolyzed to form optically active aspartic acid(V). The optical purity of V reached up to 49 %.
