In search of novel pyrazole oxime ether derivatives with potent bioactivities, fifteen new pyrazole oxime ethers were designed and synthesized by introducing 1,3,4-oxadiazole moiety into the C-4 position of pyrazole based on the structure of fenpyroximate. Their structures were confirmed by 1H NMR, 13C NMR and elemental analysis. Preliminary bioassay data showed that some title compounds possessed good insecticidal activities against Oriental armyworm or Aphis medicaginis at the concentration of 500 and 100 μg/mL. At 100 μg/mL, compounds 10a, 10e, 10f and 10j displayed 100% mortality rate against Oriental armyworm, and compounds 10g, 10j and 10l showed insecticidal activity against Aphis medicaginis with 100%. In addition, compound 10l had 100% mortality rate against Tetranychus cinnabarinus at 500 μg/mL.

Key words: 1,3,4-oxadiazole, pyrazole oxime ether, synthesis, insecticidal activity
