Total synthesis of a lanthionine peptide nisin was achieved by the successive condensations of four segments including cyclic lanthionine peptide parts and the C-terminal linear segment including dehydroalanine, followed by the deprotection procedure with anhydrous HF. Modified reaction conditions for the Hofmann degradation were applied to prepare the dehydroalanine residue from the 2,3-diaminopropionic

硫氨酸肽
乳链菌肽的全合成是通过包括环状羊毛
硫氨酸肽部分和 C 端线性部分(包括
脱氢丙
氨酸)在内的四个部分的连续缩合,然后用无
水 HF 进行
脱保护程序来实现的。应用改进的霍夫曼降解反应条件从

水HF进行最终
脱保护,
脱氢氨基酸残基没有分解,
脱氢氨基酸残基通常在酸性介质中不稳定。合成
乳链菌肽在所有方面都与
天然乳链菌肽完全相同,从而证实了所提出的结构。
