Methyl 2-deoxy-2-isothiocyanato-alpha-D-glucopyranoside 2, which exists in equilibrium with the corresponding 2,3-cyclic carbamate 1, reacts with D-glucosamine producing the pseudo-C and N-nucleoside of chiral imidazolidine-2-thione 3, in good yield and high stereoselectivity. Starting from 3, different pseudo-C- and N-nucleosides of imidazoline-2-thione 6-11, and of imidazole 12 and 13 are obtained. Conformational aspects of some of the prepared compounds are discussed.
