The first total synthesis of lineaflavones A, C, D, and their analogues has been accomplished. The key synthetic steps include aldol/oxa-Michael/dehydration sequence reactions to assemble the tricyclic core, Claisen rearrangement and Schenck ene reaction to construct the key intermediate, and selective substitution or elimination of tertiary allylic alcohol to obtain natural compounds. In addition
首次完成了线黄酮A、C、D及其类似物的全合成。关键合成步骤包括羟醛/氧杂-迈克尔/脱水顺序反应组装三环核心,克莱森重排和申克烯反应构建关键中间体,选择性取代或消除叔烯丙醇得到天然化合物。此外,我们还探索了5条新路线合成了53种天然产物类似物,有助于在生物学评价中建立系统的构效关系。
