Abstract

Certain1-hepta-O-benzoyl-β-D-lactosyl-5-substituted-2-S-benzyl-2-isothiobiurets have been synthesized for the first time by the interaction of 1-hepta-O-benzoyl-β-D-lactosyl-2-S-benzyl isothiocarbamide with various isocyanates. The structures of these new 2-isothiobiurets have been established on the basis of usual chemical transformations and IR, NMR, and Mass spectral analysis. The polarimetric study of title compounds has been carried out.
