Comparative study of microwave induced and conventional synthesis of acetylated sugar isothiocyanates and related thiocarbamides
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.

Raney Nickel Desulphuration of 1-Substituted- and 1,3-Disubstituted-thioureas
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.
