Serendipitous Synthesis of N-Tetrachlorophthaloyldehydroalanine Methyl Ester, a Michael Acceptor which is a Potential Precursor of γ-Carboxyglutamic Acid
Abstract
An attempt to synthesise a new protected serine derivative led to the isolation of N-tetrachlorophthaloyldehydroalanine methyl ester, which underwent Michael addition of dialkyl malonates to form γ-carboxyglutamic acid derivatives.
