Synthesis of pyrazolotriazolopyrimidine tri-fused heterocyclic compounds

This paper uses basic-catalysed method to convert 1H-pyrazole-4-carboxamides into tri-fused heterocyclic systems containing two kinds of pyrazolotriazolopyrimidine framework. The synthesis of compounds 5-6 and reactions of them with some electrophiles hav

Convenient Preparation of Novel Fused Tri-heterocyclic Compounds

Novel pyrazolotriazolopyrimidine and dipyrazolopyrimidine fused triheterocyclic compounds were prepared in a convenient method and in good yields. The structures of the title compounds were confirmed by elemental analysis, 1H NMR, 13C NMR, IR and MS. Preliminary bioassay study showed that some compounds displayed high inhibition to mosquito (10 ppm).
