Description

(S)-4-Methyl-2,5-oxazolidonedione is also known as N-Carboxy anhydrides. The Fuchs-Farthing method, reported in 1922, was the only practical method for preparing (S)-4-Methyl-2,5-oxazolidonedione[1]. N-Carboxy anhydrides (NCAs) are important as α-amino acid building blocks for the synthesis of oligopeptides and nonpeptide compounds, and for the synthesis of polypeptides[2]. The polymerization of NCAs is the main process for the preparation of polypeptides, and its purity and side chains can significantly affect the synthesized polypeptides. NCAs polymerizations have been initiated using many different nucleophiles and bases, the most common being primary amines and alkoxide anions[3].
