Abstract The four 5,6-dideoxy-6-halogeno-1,2- O -isopropylidene-3- O -methyl-α- d - xylo -hept-5-eno-1,4-furanurononitriles (bromo, chloro, fluoro, and iodo) were prepared by treatment of 1,2- O -isopropylidene-3- O -methyl-α- d -pentodialdo-1,4-furanose with the corresponding (cyanohalogenomethylene)triphenylphosphorane. The geometrical isomers were separated by liquid chromatography. Spectral data
