A systematic synthesis of 3-phenylimino-4-phenyl-5-tetra-O-acetyl-β-D-glucopyranosylimino-1,2,4-dithiazolidine (acetylated glucopyranosylimino nucleoside) from glucose as starting material. The steps included acetylating glucose to glucose penta-acetate (II). Step 2 involves the bromination of glucose penta-acetate (II) to 2,3,4,6 tetra-O-acetyl-α-D-glucopyranosyl bromide (III). In step 3 compound (III) reacted with lead thiocyanate to give 2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl isothiocyanate (IV). In the step 4 N-phenyl-3-tetra-O-acetyl-β-D-glucopyranosyl isothiocyanate (V) was prepared. In the last step on refluxing compound (V) with N-phenyl S-chloro isothiocarbamoyl chloride to yield acetylated glucopyranosyl nucleoside. Furthermore de-acetylating of acetylated glucopyranosyl nucleoside was carried out to obtain 3-phenylimino-4-phenyl-5-β-D-gluopyranosyl imino 1,2,4-dithiazolidine (de-acetylated glucopyranosylimino nucleoside). The synthesized acetylated glucopyranosylimino nucleoside and deacetylated glucopyranosylimono nucleoside were structurally confirmed by elemental analysis, ultraviolet spectral analysis, infrared spectroscopy, nuclear magnetic resonance spectroscopy and mass spectroscopy.

The synthesis of several acetylated sugar isothiocyanates have been carried out under microwave irradiation in excellent yields of products by using related bromides and lead thiocyanate in sodium dried xylene. Several acetylated sugar thiocarbamides have been synthesized by the interaction of respective acetylated sugar isothiocyanates with appropriate aryl amines under microwave irradiation.

Certain 1-aryl-1,3-diaryl- and 1-aryl-3-tetra-O-acetyl-β-D-glucopyranosyl thioureas have been successfully desulphurated into the related mono- and 1,3-di-substituted formamidines with the help of Raney nickel catalyst.A few of them have been converted into the corresponding formamides also.Structure of the products have been established through usual chemical transformations, ir, nmr and mass spectral analysis.
