A stereoselective synthesis of the proposed structure of palmerolide C (1), a cytotoxic marine macrolide isolated from the Antarctic tunicate Synoicum adareanum, utilizes a convergent carbonyl‐based coupling strategy to construct the C1–C24 carbon skeleton (see scheme). Compound 1 was shown to be a diastereomer of palmerolide C, and the structural revision of the natural product is proposed.
拟议的棕榈油酰内酯C(1)的结构的立体选择性合成,是一种从南极被膜类植物金龟子分离的细胞毒性海洋大环内酯,利用会聚的基于羰基的偶联策略构建C1-C24碳骨架(参见方案)。已显示化合物1是棕榈油内酯C的非对映异构体,并提出了天然产物的结构改进方案。
