Abstract
Recently, metallaphotoredox-catalyzed alkene dicarbofunctionalization reactions have been extensively investigated. Most cases are related to alkyl-arylation processes by conjugate coupling of alkyl radical precursors and aryl electrophiles across alkenes. By contrast, reported examples of alkylvinylation by coupling of vinyl electrophiles are largely limited. Herein, we represent a three-component aminoalkyl-vinylation of alkenes enabled by photoredox/nickel catalysis. This redox-neutral protocol exhibits broad substrate scope and good chemo-, regio- and E/Z-stereoselectivity. A series of valuable α-vinyl γ-amino acid derivatives are conveniently synthesized by the assembly of readily available starting materials.
