N-Carboxy α-dehydroamino acid anhydride, derived from N-benzyloxycarbonyl α-dehydroamino acid (DHA) and thionyl chloride, was found to be very useful for the synthesis of N-free DHA ester by alcoholysis and N-acetyl dehydrodipeptide ester by coupling was α-amino acid ester.
N-羧基 α-脱氨基酸酸酐是由 N-苄氧羰基 α-脱氨基酸(DHA)和氯化亚硫酰制得的,发现它在通过醇解合成无氮 DHA 酯和通过偶联合成 N-乙酰脱二肽酯时非常有用。
