We report herein an efficient protocol for the synthesis of N-urethane-protected α-amino/peptide thioacids from their corresponding acids mediated by EDC and Na2S. The fast reaction under mild conditions enabled the process to be completed in shorter duration with good yield circumventing column purification. The chemistry is compatible with a wide variety of urethane protecting groups, side-chain functionalities, and sterically hindered amino acids.
本文报道了一种高效的方法,通过EDC和Na2S介导,从相应的酸合成N-urethane保护的α-氨基酸/肽硫酸酯。在温和条件下快速反应使得该过程能在较短时间内完成,且产率良好,无需柱层析纯化。该化学方法适用于多种urethane保护基团、侧链功能团以及空间位阻氨基酸。
