Synthesis and insecticidal activity of trifluoromethyl-isoxazoline compounds

16 Novel trifluoromethyl-isoxazoline compounds were synthesized by 1,3-dipolar cycloaddition of substituted(1-trifluoromethyl-vinyl)-benzene with substituted cinnamic aldehyde oxime.Their structures were confirmed by 1H NMR and LC-MS.The bioassay showed that most of the compounds exhibit some activity against Prodenia litura and Mythimna separate at the concentration of 500 mg/L,among them,the mortality of ZJ11 against M.separate was 100%,even 80% at 100 mg/L.
