to access tetrahydropyran-containing macrolactones in a single step from readily available linear precursors. To illustrate the feasibility of the synthetic strategy, an antitumor marine macrolide, (−)-exiguolide, was synthesized in just 13 steps from a commercially available compound.
开发了一种集成了 Meyer-Schuster 重排、大环闭环复分解和跨环 oxa-Michael 加成的催化串联反应,可从现成的线性前体一步获得含四氢吡喃的大环内酯。为了说明该合成策略的可行性,一种抗肿瘤海洋大环内酯类 (-)-exiguolide 由市售化合物仅用 13 个步骤合成。
