Visible-light-induced iodine-anion-catalyzed decarboxylative/deaminative C–H alkylation of enamides

Abstract

A visible-light-induced iodine-anion-catalyzed C–H stereoselective alkylation of enamides has been developed. Redox-active esters and Katritzky salts of amino acids were found to be amenable for decarboxylative/deaminative cross-coupling reactions, delivering various functionalized enamides with excellent functional group tolerance. The reaction proceeded via photoactivation of the transiently assembled chromophores, avoiding the use of exogenous precious photoredox catalysts.
