-beta-D-fructofuranose 1,2':2,1'-dianhydride were respectively obtained, on a preparative scale, by dissolution of the isomericglycosylfructoses palatinose, leucrose, maltulose, lactulose, and turanose in anhydroushydrogenfluoride. The reaction, involving selectiveprotonation at the free anomeric position of the fructose unit, was extended to the preparation of the pseudotrisaccharides 6-O-alp
