Not one, not two, but three: Total syntheses of amphidinolides B, G, and H, which exhibit strong, nanogram‐scale cytotoxicity against various tumor cell lines, have been executed. The synthetic strategy relied on implementation of a diene construction protocol and a diastereoselective aldol process. The 26‐ and 27‐membered macrocyclic lactone rings were efficiently constructed by using ring‐closing
不是一个,不是两个,而是三个:已执行了对两类肿瘤细胞系表现出强大的纳克级细胞毒性的两性霉素B,G和H的总合成。合成策略依赖于二烯构建方案和非对映选择性羟醛工艺的实施。使用闭环复分解(RCM)可有效构建26和27元大环内酯环。
