A straightforward approach to synthesise of isocoumarins via Rh(III)-catalyzed C-H/C-C bond acitvation/annulation cascade of enaminones and iodonium ylides has been explored. The established protocol is characterized by an exceedingly simple...

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 under mild reaction conditions, providing a straightforward approach to access structurally diverse and valuable N-alkyl indole derivatives.
