Stannylation of 2,3-O-isopropylidene-.beta.-D-fructopyranose with dibutylin oxide followed by brominolysis afforded 2,3-O-isopropylidene-.beta.-D-threo-hexo-2,4-diulopyranose, which was characterized as its oxime. Brominolysis of the O-dibutylstannylene derivative of 1,2-O-isopropylidene-.beta.-D-fructopyranose furnished 1,2-O-isopropylidene-.beta.-D-threo-hexo-2,5-diulopyranose, which was characterized as the corresponding O-methyloxime diacetate.
