Visible-light-mediated defluorinative cyclization of α-fluoro-β-enamino esters catalyzed by 4-CzIPN

Using 4-CzIPN as an energy transfer (EnT) photocatalyst and α-fluoro-β-enamino esters as substrates, a mild 6π-photocyclization/defluorination of N -aryl enamines was carried out to efficiently construct indoles without an oxidant and a transition metal catalyst under visible light irradiation. Mech...
