A novel protocol for synthesizing N-alkyl indoles from readily available N-nitrosoanilines and iodonium ylides through the rhodium(III)-catalyzed C–H bond activation/intramolecular cyclization reaction has been described. This strategy employs nitroso as a traceless directing group. The transformation features powerful reactivity, tolerates various functional groups, and proceeds with moderate yields
