The first enantioselective organocatalytic carbo-oxidation of styrenes has been accomplished using singly occupied molecular orbital (SOMO) catalysis. Geometrically constrained radical cations are generated from the one-electron oxidation of enamines formed from the condensation of aldehydes with a secondaryamine catalyst. These SOMO-activated radical cations are susceptible to attack by commercially
