Abstract

1311241 Aspartic and glutamic anhydride hydrohalides AJINOMOTO CO Inc 19 April 1971 [16 Feb 1970 30 March 1970] 21594/71 Heading C2C A hydrohalide of aspartic or glutamic anhydride is prepared by reacting aspartic or glutamic acid with a halogen-containing dehydrating agent in an inert organic medium. Suitable dehydrating agents are phosphorus halides and halides of oxyacids of carbon, sulphur or phosphorus. α-Methyl-L-aspartate was obtained by dissolving L-aspartic anhydride hydrochloride in methanol.
