Reaction of reducing disaccharide peracetates 1, 5, 9 and 13 with hydr
azine hydrate in acetonitrile gave predominantly the corresponding hep
taacetates 2, 6, 10 and 14, with the free hydroxyl group at C-l or the
hexaacetates 3, 7, 11 and 12, with the hydroxyl groups at C-1,2 or C-
1,3 and the pentaacetates 4 and 8 with the hydroxyl groups at C-1,2,3,
depending on the quantity of reagent used.
