Photoredox/NHC-catalyzed remote alkylation of γ-functionalized enals with N-substituted pyridinium salts.

We report a dual photoredox/NHC-catalyzed method for the regioselective remote alkylation of γ-functionalized enals. Using abundant Katritzky pyridinium salts as alkyl radical precursors and γ-functionalized enals to form trienolate intermediates, th…
