Hydrocarbazolone and its derivatives are attractive organic molecules, which have been
widely applied in the synthesis of natural products and pharmaceuticals. Herein, we …

We report herein a photoinduced carboborative ring contraction of monounsaturated six-
membered carbocycles and heterocycles. The reaction produces substituted five-membered …

Herein, we report a protocol for visible-light-induced dearomative oxamination reactions of
indole derivatives to afford functionalized spirocyclic products. These step-economical …

Described herein is a redox-neutral intramolecular dearomative spirocyclization induced by
visible light. The photochemical cyclization was catalyzed by a phenolate anion-derived …

A photocatalytic tandem cyclization of o-alkenylbenzaldehydes using pyridinium salts as the
amination reagent is described. A variety of valuable seven-membered nitrogenous …

A mild metal-, catalyst-, and oxidant-free photoredox neutral system has been found to
efficiently enable intramolecular decarboxylative cyclization of anthranilic acids. This facile …

The dearomative cyclization of linear amides to complex spirocyclic butyrolactams has been
enabled by photoredox catalysis through a reductive radical–polar crossover mechanism …
