Radical Deoxygenative Three-Component Reaction of Alcohols, Aryl Alkenes, and Cyanopyridines

Abstract

We report herein a deoxygenative radical multicomponent reaction involving alcohols, aryl alkenes, and cyanopyridine under photoredox conditions. This method is photoredox-neutral, suitable for late-stage modification, and compatible with a wide array of alcohols as alkyl radical sources, including primary, secondary, and tertiary alcohols. This reaction comprises a radical relay mechanism encompassing the Giese addition of aryl alkenes by alkyl radicals, followed by the decyanative pyridination of benzyl radicals.
