A one-step procedure using methyl cyanoformate and a secondary alkylamine was reported to efficiently transform ketones into O-methoxycarbonyl cyanohydrins. This functional group shows interesting potential in protecting group chemistry.

O-Methoxycarbonyl cyanohydrin, a newprotectivegroup of carbonyls, was prepared in high yields by an efficient one-step procedure using methyl cyanoformate and a secondary alkylamine at room temperature. Herein, we report efficient methods for the formation and cleavage of the protectivegroup. Also, the ability of different types of carbonyls to be protected and the protectivegroup's behavior under different
