Synthesis of nucleoside analogs from hydrazine derivatives

Reaction of 6-hydrazino-l,3-dimethyluracil (1) with glycosyl isothiocyanates (2a,b,c) gave the glycosyl thiosemicarbazides (3a,b,c) in good yield, which were cyclized to pyrimidothiadiazines (5a,b,c) with NBS oxidation. And 5a,b,c were converted to pyrazolopyrimidines (6a,b,c) by thermal desulfuriza...
