entry to eight types of bridged tetracyclic skeletons bearing various ring sizes and heterocycles. With this method, several skeletons or analogs of natural products including tubingensin B and dracaenones are synthesized. Asymmetric dearomative cyclization enables various enantiomerically enriched bridged polycyclic systems with up to 99% ee by employing a chiral palladium catalyst.
开发了功能强大的钯催化脱芳香环化反应,可轻松进入八种带有各种环尺寸和杂环的桥连四环骨架。用这种方法,合成了几种天然产物的骨架或类似物,包括微管蛋白B和龙血烯酮。通过使用手性钯催化剂,不对称脱芳香环化反应使各种对映体富集的桥联多环体系的ee高达99%。
