Sustainable electrochemical dearomatization for the synthesis of diverse 2, 3-functionalized indolines

Herein, we achieved a green and efficient dearomatization for the synthesis of 2,3-functionalized polycyclic indolines in an electrochemical way. This avoiding of external oxidants and metals approach allowed various nucleophilic sources (Nu ​= ​anilines, TMSN3 and ROH) to perform the products, representing an environmentally benign means. Additionally, the continuous flow electrosynthesis and synthetic transformations also reveal the strong practicality of electrochemistry in organic synthesis.
