azaarenes through an in situ activation strategy, which not only achieved the first full exploitation of the reactive sites of the azaarenes, but also accomplished the efficient synthesis of bridged hydrogenated pyridines and (iso)quinolines in a highly regioselective and diastereoselective manner. In addition, we could successfully realize the step-controlled dearomative trifunctionalization and bifunctionalization
本文报道的是一种通过原位活化策略实现的市售氮杂芳烃前所未有的多组分单锅脱芳香化多功能化,不仅实现了氮杂芳烃反应位点的首次充分利用,而且还实现了桥联氢化吡啶和(异)喹啉具有高度区域选择性和非对映选择性的方式。此外,我们可以成功实现喹啉的分步控制脱芳香三官能化和双官能化。
