Abstract
The structure of (4 R)-1-aryl-5-hydroxy-4-( d- arabino-tetritol-1-yl)imidazolidine-2-thiones ( 1–3), obtained by reaction of 2-amino-2-deoxy- d-glucose with aryl isothiocyanates, has been confirmed by 1H- and 13C-n.m.r. spectroscopy. Likewise, the structures of 2-(3-benzoylthioureido)-2-deoxy- d-glucopyranose and 2-deoxy-2-(3-phenylureido)- d-glucopyranose, prepared by reaction of 2-amino-2-deoxy- d-glucose with benzoyl isothiocyanate and phenyl isocyanate, respectively, were also established. An X-ray analysis of 1–5 R (aryl = phenyl) has been carried out and its conformation in the solid state is one of the preponderant conformations in solution.
