The reaction of ammonia with acylated disaccharides : Part X. Octa- O-benzoyl-lactose and other benzoyl derivatives of lactose

Abstract

From the reaction of octa- O-benzoyl-lactose ( 1) with methanolic ammonia, lactose, 1,1-bis(benzamido)-1-deoxy-4- O-β- D-galactopyranosyl- D-glucitol ( 2), and N-benzoyl-4- O-β- D-galactopyranosyl- D-glucopyranosylamine ( 3) were obtained. The behavior of some other octabenzoylated disaccharides in the ammonolysis reaction is discussed.
