The BCD tricyclic core of brownin F was prepared in eight synthetic operations for the first time. Our synthesis features a diastereo-, chemo- and regioselective intramolecular [3 + 2] cycloaddition between a cyclic carbonyl ylide and a γ-alkylidenebutenolide.
首次经过八次合成操作制备了 Brownin F 的 BCD 三环核心。我们的合成以环状羰基叶立德和γ-亚烷基丁烯内酯之间的非对映、化学和区域选择性分子内[3 + 2]环加成为特征。
