Asymmetric cross-dehydrogenative coupling (CDC) of C(sp3)–H bonds shows great potential for rapid and stereoselective construction of C–Cbonds and use of molecular oxygen as the oxidant for such transformations is appealing in the context of green synthetic methodologies. However, the poor reactivity of oxygen at the ground state and the challenges in controlling the stereochemistry make it extremely
