A general strategy for the synthesis of cyclopeptide alkaloids containing an endocyclic aryl-alkyl ether bond has been developed featuring a key intramolecular S(N)Ar reaction. The importance of the N-terminal protective group in the realization of such a strategy is documented. From the appropriate amino acid constituents, the natural sanjoinine G1, a 14-membered para cyclophane, has been synthesized
已开发出合成包含环内芳基-烷基醚键的环肽生物碱的一般策略,其特征在于关键的分子内 S(N)Ar 反应。N-末端保护基团在实现这种策略中的重要性被记录在案。从适当的氨基酸成分中,天然三连宁 G1,一种 14 元对环芳烷,已分七个步骤合成,总产率为 21%。
