Photoredox‐Initiated α‐Alkylation of Imines through a Three‐Component Radical/Cationic Reaction

Radical-polar crossover reaction: The photoredox-mediated alkylation of enamides with diethyl bromomalonate in the presence of alcohols has been developed. This multicomponent domino process affords β-alkylated α-carbamido ethers as stables imine surrogates in good to excellent yields under mild conditions (see scheme).
