  Design, Synthesis, and Insecticidal Evaluation of New Benzoylureas Containing Isoxazoline and Isoxazole Group

  摘要：

  Twenty-two new benzoylphenylureas containing isoxazoline and the isoxazole group were designed and synthesized, and their structures were characterized by (1)H NMR and elemental analysis (or FIRMS). The larvicidal activities against Oriental armyworm, mosquito, and diamondback moth of the new compounds were evaluated. Compounds I-1 and III-1 showed nearly the same level of insecticidal activity against Oriental armyworm as commercial insecticide Flucycloxuron and surprisingly exhibited much higher larvicidal activities against diamondback moth than Flucycloxuron.

  4-nitrobenzonitrile oxide (2) which was generated in situ with acrylo nitrile (3), methyl methacrylate (4) and allyl bromide (5) as dipolarphile afforded the new 7a, 8a and 9a compounds respectively. Reactivity and regiochemistry of these reactions were investigated using activation energy calculations and density functional theory (DFT)-based reactivity indexes.

  isoxazolines has been reported. Aryl aldoximes were made to react with alkenes in the presence of \(\hbox KIO}_3}\) as the oxidising agent. This new reagent has been useful as an oxidant in the synthesis of isoxazoline and its function is attributed to the generation of nitrile oxide, which is an important intermediate for the synthesis of the valuable heterocycle like isoxazoline.
