Photoredox catalyzed synthesis of β-trifluoromethyl β-aminoketones from N-trifluoroethyl hydroxylamine reagent and silyl enol ethers

Abstract

This study presents a photoredox-catalyzed two-component alkylative coupling between silyl enol ethers and an N-trifluoroethyl hydroxylamine reagent via a radical 1,2-H shift, establishing a novel synthetic route toward β-trifluoromethyl β-aminoketones. The protocol offers exceptional efficiency, mild reaction conditions, and operational simplicity.
