In this study, the total synthesis of osajin, scandenone and their analogues have been accomplished. The key synthetic steps include aldol/intramolecular iodoetherification/elimination sequence reactions and a Suzuki coupling reaction to assemble the tricyclic core, chemoselective propargylation and Claisen rearrangement reactions to obtain natural compounds. In addition, we also designed and synthesized
本研究完成了osajin、scandenone及其类似物的全合成。关键的合成步骤包括羟醛/分子内碘醚化/消除序列反应和铃木偶联反应以组装三环核心,化学选择性炔丙基化和克莱森重排反应以获得天然化合物。此外,我们还设计合成了二十五种天然产物类似物。所有合成化合物均在脂多糖 (LPS) 刺激的 RAW264.7 巨噬细胞中筛选针对肿瘤坏死因子-α (TNF-α) 和白细胞介素 6 (IL-6) 的抗炎活性。总的来说,化合物 39e 和 39d 被认为是有希望进一步开发的先导化合物。
