Filipin III (1), a polyene macrolide antibiotic, has been synthesized for the first time. The polyol chain was assembled using a stereoselective carbon-carbon bond forming strategy previously developed in our lab: a cyanohydrin acetonide alkylation and reductive decyanation sequence. The polyene segment was prepared from L-ascorbic acid. These two components were coupled using Yamaguchi's esterification
首次合成了多烯大环内酯类抗生素Filipin III(1)。使用先前在我们实验室中开发的立体选择性碳-碳键形成策略组装多元醇链:氰醇丙酮丙酮化物烷基化和还原性脱氰序列。多烯链段由L-抗坏血酸制备。使用山口的酯化作用将这两个组分偶联,并通过分子内霍纳-埃蒙斯反应进行环化以形成三取代的烯烃。立体选择性还原,然后脱保护,得到菲林III。这种高度融合的菲律宾III方法代表了甲基戊烯大环内酯类抗生素的第一个全合成。
