Abstract
Novel pyrazolotriazolopyrimidine and dipyrazolopyrimidine fused tri‐heterocyclic 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).
