Catalytic Radical Cation Salt Induced C_sp³–H Functionalization of Glycine Derivatives: Synthesis of Substituted Quinolines

A domino C_sp³–H functionalization of glycine derivatives was achieved under catalytic radical cation salt induced conditions, producing a series of quinolines. The proposed mechanism shows that a peroxyl radical cation, which is generated by the coupling between O₂ and TBPA^+•, might be involved to initiate the catalytic oxidation
