its 6-pyruvoylation is described. Photolysis of this ester in benzene furnished 5,6- O -isopropylidene-β- d - lyxo -5-ulofuranose, characterised as the O -methyloxime diacetate. Similary, photochemical oxidation of 1 1,2- O -isopropylidene-6- O -pyruvoyl-α- d -glucofuranose gave 1,2- O -isopropylidene-α- d - lgluco -hexodialo1,4:6,3-difuranose in excellent yield.
