The preparation of cyclic hexapeptides from N-hydroxy tripeptides building blocks is described. Introduction of an unsaturated chain on the hydroxamate oxygen followed by fragment coupling leads to N,N'-dialkenoxy hexapeptides that are efficiently cyclized through a ring-closing metathesis reaction. The length of the alkene chains allows the modulation of the ring size: the synthesis of 17- and 18-membered
描述了由N-羟基三肽结构单元制备环状六肽。在异羟肟酸酯氧上引入不饱和链,然后进行片段偶联,生成N,N'-二烯氧基六肽,可通过闭环易位反应有效地环化。烯烃链的长度允许调节环的大小:报道了17和18元环的合成。
