A concise catalytic asymmetric synthesis of the proposed structure of trocheliophorolide B is reported. The synthetic sequence notably features an asymmetric acetaldehyde alkynylation, a Ru-catalyzed alder–ene reaction, and a Zn-ProPhenol ynone aldol condensation. Comparison with the reported data suggests a misassignment of the natural product structure.
报道了所提出的 trocheliophorolide B 结构的简明催化不对称合成。合成序列的显着特点是不对称乙醛炔基化、Ru 催化的桤木-烯反应和 Zn-ProPhenol 炔酮醇醛缩合。与报告数据的比较表明天然产物结构的错误分配。
