A switchable redox annulation of 2-nitroarylethanols affording <i>N</i>-heterocycles: photoexcited nitro as a multifunctional handle

Abstract

generated nitroso species. The utility of this protocol was well demonstrated by broad substrate scope, excellent yields, functional group tolerance and wide applications. Finally, detailed mechanistic studies were performed, and kinetic isotope effect (KIE) experiments indicate that the homolysis of the C-H bond is involved in the rate-determining step.
