profile of alkylhalides has led to the development of a new method for the asymmetric synthesis of chiral heterocyclic aminoacids. This protocol involves the asymmetric alkylation of the Ni(II) complex of glycine to form an intermediate, which then decomposes to form a series of valuable chiral aminoacids in high yields and with excellent diastereoselectivity. The chiral aminoacids underwent a
