Sulfinate-assisted, photoredox-catalyzed insertion of alkenes into the C–N bond of acyl azoles

Abstract

A selective insertion of alkenes into the C–N bond of acyl azoles by sulfinate assisted photoredox catalysis is effectively established for affording β-aminoketones under transition metal- and oxidant-free conditions. The transformation is readily scalable, and the resulting products can be diversified into other valuable frameworks, underscoring its practicality.
