By using (N-tosyloxy)-3-O-carbamoyl-o-glucal 10, which removes the :need for a hypervalentsiodine (III) oxidant, we provide evidence for rhodium nitrenoid-mediated ipso C-H activation as the origin of a C3oxidized dihydropyranone product 3. 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.
