Six novel thiosemicarbazones containing sugar and thiosemicarbazide moieties were synthesized by a five-step procedure using %D%-galactose and %D%-xylose as the starting materials and the corresponding glycosyl isothiocyanates as the intermediates. The target compounds were characterized by IR, {}~1H NMR, and elemental analysis. The coupling constants between H1 and H2 in the sugar rings, all fall within the range of J=9.2_10.0 Hz, confirming the β-configuration of the compounds.
