Synthesis of α- and β- N-oxalyl- l-α,β-diaminopropionic acids and their isolation from seeds of Lathyrus sativus

Abstract

The α- and β- N-oxalyl derivatives of l-α,β-diaminopropionic acid have been chemically synthesized and also isolated from seed extracts of Lathyrus sativus. Chemical and physical properties of the natural and synthetic isomers were in good agreement. The toxicity of the α-isomer to chicks was evaluated and compared with that of the β-isomer.
