Visible‐Light‐Promoted Oxidative Alkylarylation of N‐Aryl/Benzoyl Acrylamides Through Direct C−H Bond Functionalization

Abstract Radical cascade oxidative alkylarylations of N ‐aryl/benzoyl acrylamides have been established through visible‐light‐enabled photocatalysis, furnishing a wide variety of functionalized oxindoles and isoquinolinediones in good‐to‐excellent yields under the synergistic interactions of an organic fluorophores‐type photocatalyst 4CzIPN, trifluoroacetoxyiodobenzene (PIFA), and 1,3,5‐trimethoxybenzene with visible light irradiation. The prominent features of this method are the broad substrate scope, excellent functional group tolerance, and mild reaction conditions. magnified image
