Synthesis of some pyrazolo[3,4-d]pyrimidines and their fused triazole and tetrazole derivatives

Synthesis of some pyrazolo[3,4-d]pyrimidines and their fused triazole and tetrazole derivatives

Reaction of 2 with different reagents, namely formic acid, acetic anhydride and trichloroacetonitrile, yielded pyrazolo[3,4-d]pyrimidine derivatives 3, 5 and 6, respectively. Pyrazolo[3,4-d]pyrimidine m-thiazine(7) and 2,4-(1H,3H)dithione (8) derivatives were formed by the action of carbon...
