Concise syntheses of the natural products cavicularin (ten steps) and riccardin C (seven steps) are reported. Key features of the new synthetic route are a convergent strategy to assemble acyclic precursors and a sequence of regioselective reduction and halogenation steps to facilitate Wittig macrocyclisation and transannular ring contraction reactions.
报告了天然产物 cavicularin(十步)和 riccardin C(七步)的简洁合成。新合成路线的关键特点是一种汇聚策略,用于组装无环前体,以及一系列区域选择性还原和卤化步骤,以促进 Wittig 大环化和反环缩合反应。
