摘要: A process for synthesizing substantially enantiomerically pure L-amino acids, particularly L-γ-methylene glutamic acid, and esters and salts thereof. The process includes the derivatization of (2S)-pyroglutamic acid, and the decyclization of the resulting derivative to form the desired end product.
