Asymmetric CDC Reaction of Benzylic ---H Bonds

On the basis of the cyclic voltammetry (CV) results, DFT calculations, and control experiments, the reaction mechanism involving the cationic radical enamine was proposed. 

In 2010, Gong and co-workers reported a Lewis acid-catalyzed enantioselective oxidative cross-coupling reaction of 3-indolylmethyl C—H bonds
