SYNTHESIS OF γ‐CARBOXYGLUTAMIC ACID AND ITS DERIVATIVES VIA MANNICH‐BASE CONDENSATION

Abstract
This report describes the synthesis of Nα-formyl and Nα-benzyloxycarbonyl-γγ-di-t-butyl-γ-carboxyglutamic acid via Mannich-base condensation starting from di-t-butyl malonate and diethyl formamido or benzyloxycarbonylamidomalonate.
