The asymmetric organocatalyzed a-alkylation of aldehydes via a cationic radical enamine intermediate was performed under environmentally benign electro-oxidation conditions without the use of chemical, oxidants. To promote the desired a-alkylation reaction of aldehydes, various aldehydes with xanthene or cycloheptatriene groups were exposed to elec-tro-organocatalytic conditions to afford optically active αsubstituted aldehydes (α-alkylated aldehydes) in good yield. A reaction mechanism involving the cationic radical enamine was proposed based on the cyclic voltammetry (CV) results, DFT calculations, and control experiments.
