hypoiodite-catalyzed tandem dearomative peroxycyclization of homotryptamine derivatives to peroxytetrahydropyridoindolenines under mild conditions. During the course of a mechanistic study, we found that a tandem oxidative cyclization/epoxidation as an unexpected reaction proceeded in the presence of TEMPO as an additive. Intramolecularoxidative aminocyclization of homotryptamines at the C-2 position would give
