A new MnO2-catalyzed oxidative alkylation of enamides with a C(sp3)–H bond adjacent to an oxygen atom is described. This method achieves a C(sp3)-H/C(sp2)-H cross-dehydrogenative coupling and hydrolysis, thus providing efficient and general access to a variety of β-oxo ketones.

A newer synthetic protocol has been developed to synthesize α-oxyalkyl ketonesfromvinylazides under transition-metal-free reaction conditions. The reaction proceeds in the presence of organic photoredox catalyst rose bengal, an oxidant tert-butyl hydroperoxide (TBHP), and ethers. A broad range of substituted vinylazides were found to react smoothly upon visible-light irradiation, which readily
