By using (N-tosyloxy)-3-O-carbamoyl-d-glucal10, which removes the need for a hypervalent iodine(III) oxidant, we provide evidence for rhodium nitrenoid-mediatedipsoC−H activation as the origin of a C3-oxidized dihydropyranone product3. This system may be especially susceptible to such a pathway because of the ease of forming a cation upon hydride transfer to the rhodium-complexed acyl nitrene.
