The first systematic study on metal-carbene transfer reaction of 7-azaindoles has been conducted, and the unprecedented dearomative N7-alkylation reaction has been accomplished via ruthenium catalysis. Importantly, through a sequential dearomatization–aromatization process, an isolable, and new class of azaindole-based N-aromatic zwitterions has been discovered from the reaction of 7-azaindoles and diazoesters.

通过碳原子转移和分离N-芳族两性离子实现7-氮杂吲哚的位点选择性官能化

进行了7-氮杂吲哚的金属-卡宾转移反应的首次系统研究，并且通过钌催化完成了前所未有的脱芳香性N7-烷基化反应。重要的是，通过顺序的脱芳香化-芳香化过程，从7-氮杂吲哚与重氮酸酯的反应中发现了一种可分离的新型基于氮杂吲哚的N-芳香族两性离子。
