Studies towards the synthesis of the macrocyclic core of (-)-zampanolide are reported. The synthetic approach features a one-pot reduction/vinylogous aldol reaction for construction of the C15-C20 fragment, an intramolecular silyl-modified Sakurai (ISMS) reaction for construction of the 2,6-cis-disubstituted exo-methylene pyran subunit, and use of an sp2-sp3 Stille reaction for macrocyclization.
报道了对 (-)-zampanolide 大环核心合成的研究。合成方法的特点是一锅还原/乙烯醇醛反应用于构建 C15-C20 片段,分子内甲硅烷基修饰的 Sakurai (ISMS) 反应用于构建 2,6-顺式二取代外亚甲基吡喃亚基,以及使用 sp2-sp3 Stille 反应进行大环化。
