Jekyll and aldeHyde: The oxidation of enamines to iminium species by 2-iodoxybenzoic acid (IBX) or 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) catalyzed by a chiral secondary amine catalyst enabled the unprecedented enantioselective β-functionalization of aldehydes with various nucleophiles in high stereoselectivity.
