Enantiopure α-substituted heterocycles are among the most prevalent scaffolds comprising a wide assortment of biologically active natural products and pharmaceuticals.Enantioselective oxidative C-H functionalization of heterocycles presents an atom-economic protocol without prior installation of activating groups,and is therefore attractive.While impressive progress has recently been achieved in the area,the substrate scope is merely limited to highly reactive heterocycles,such as N-aryl tetrahydroisoquinolines and 9H-xanthenes.
