Herein, we report a protocol for visible-light-induced dearomative oxamination reactions of indole derivatives to afford functionalized spirocyclic products. These step-economical reactions, which involve C–N and C–O bond formation, feature mild conditions, a broad substrate scope, high yields, exclusive diastereoselectivity and step-economy. In addition, a similar protocol could be used to synthesize spirolactams by dearomative amidation of phenol derivatives.
