A modified, high yield procedure for the synthesis of unlabeled and 14C-labeled 4-methylene-DL-glutamic acid.


This paper describes the complete chemical synthesis of 4-methylene-DL-glutamic acid from diethylmalonate, formaldehyde and diethyl acetamidomalonate. The amino acid was obtained pure following ion-exchange chromatography and/or crystallization from hot water in an overall yield of 30% based on the amount of diethylmalonate used. Several physico-chemical… (More)
