The use of 4-benzyl Hantzsch esters enables the construction of molecules with all-carbon quaternary centers by visible light-induced photoredox catalysis via transfer alkylation. Reactions of 4-alkyl Hantzsch nitriles as tertiary radical donors joined two contiguous all-carbon quaternary centers intermolecularly.
