The cascade amination/cyclization of N ‐arylacrylamides with alkyl amines under visible‐light photoredox catalysis is realized via intermediacy of aminium radicals. The aminium radicals are generated by a two‐step sequence which involves N‐chlorination of alkyl amines and subsequent reductive N−Cl cleavage. This method provides a convenient access to aminated oxindoles.
