The synthesis of alkyne- and alkene-decorated lactams has been achieved through a photoredox-initiated radical cascade reaction. The developed Brønsted base assisted, photoredox-catalyzed, intramolecular 5-exo-trig cyclization/intermolecular radical addition/elimination reaction provides facile access to functionalized γ-lactams, with good functional group tolerance and high yields.
