Abstract: Referring to the structure of RynaxypyrTM, a series of novel amides(sulfonamides) containing N-pyridylpyrazole was designed and synthesized. Their chemical structures were characterized by means of 1H NMR and elemental analysis. The results of the biological assay show that some of the amide(subfonamides) exhibite good insecticidal activities against Oriental Armyworm(Mythimna separata Walker) and Culex pipiens pallens. The death rates for Oriental Armyworm of compounds 4a, 4k and 5b are all higher than 50% at 100 mg/L, and the death rate of compound 4g for Culex pipiens pallens was 100% at 2 mg/L.

Key words: RynaxypyrTM, Amide, Sulfonamide, Biological activity
