A simple phosgene- and halogen-free method for synthesizing α-amino acid N-carboxyanhydrides (NCAs) is described. The reaction between Boc-protected α-amino acids and T3P reagent gave the corresponding NCA derivatives in good yield and purity with no detectable epimerization. The process is safe, is easy-to-operate, and does not require any specific installation. It generates nontoxic, easy to remove
描述了一种简单的光气和无卤素合成 α-氨基酸N-羧酸酐(NCAs) 的方法。Boc 保护的 α-氨基酸和 T3P 试剂之间的反应以良好的产率和纯度得到相应的 NCA 衍生物,没有可检测到的差向异构化。该过程是安全的,易于操作,并且不需要任何特定的安装。它产生无毒、易于去除的副产物。它可用于制备NCA,用于小批量或大批量的按需现场生产。
