Thirteen novel phenyl substituted isoxazolecarboxamides were synthesized,and their structures were characterized by 1 H NMR,elementary analysis and high-resolution mass spectrometry(HRMS) techniques.Their evaluated insecticidal activities against oriental armyworm(Mythimna separata) indicate that the phenyl substituted isoxazolecarboxamides exhibited moderate insecticidal activities,among which compounds 9c and 9k showed comparatively higher activities.

In search of environmentally benign insecticides with high activity, low toxicity and low resistance, a series of novel anthranilic(isophthalic) acid esters was designed and synthesized based on the structure of ryanodine modulating agent. All the compounds were characterized by 1H NMR spectra, elemental analysis or high resolution mass spectrometry(HRMS). The preliminary results of biological activity assessment indicate that some of the title compounds exhibit certain but unremarkable insecticidal activity against Mythimna separata Walker at 200 mg/L and fungicidal activities against five funguses at 50 mg/L.
