Abstract

This account provides an overview of the copper-catalyzed, K2S2O8-mediated regioselective advanced-stage benzylic C–H oxidation, a process we have named as the Bhatt–Hauser oxidation. Its impact as a synthetic method, especially in the context of the total synthesis of natural products, is presented.
