Visible-Light-Induced Photocatalytic Aerobic Oxidative Csp3-H Functionalization of Glycine Derivatives: Synthesis of Substituted Quinolines.

A visible-light induced photocatalytic aerobic oxidative dehydrogenative coupling/aromatization tandem reaction of glycine esters with unactivated alkenes has been accomplished. This visible light-driven protocol has been successfully applied to a broad scope of glycine esters and simple alkenes, giving rise to diverse substituted quinoline derivatives in 18-84% yield under mild (at room temperature under air atmosphere) and operationally simple reaction conditions.
