carbon framework of the macrocyclic marine natural product amphidinolide F has been prepared by a convergent synthetic route in which three fragments of similar size and complexity have been coupled. Key features of the syntheses of the fragments include the stereoselective construction of the tetrahydrofuran in the C1–C9 fragment by oxonium ylide (free or metal-bound) formation and rearrangement triggered
大环海洋天然产物 Amphidinolide F 的完整碳骨架是通过聚合合成路线制备的,其中三个相似大小和复杂性的片段已偶联。片段合成的关键特征包括通过氧鎓叶立德(游离或金属结合)的形成和由 1-磺酰基-1 直接生成类铑类化合物引发的重排,在 C1-C9 片段中立体选择性构建四氢呋喃, 2,3-三唑,硼烯醇化物和醛与1,4-对照之间的高度非对映选择性羟醛反应制备C10-C17片段,并通过分子内亲核开环在C18-C29片段中形成四氢呋喃在酸性条件下带有羟基的环氧化物。
