Synthesis and insecticidal activities of cis-configuration nitenpyram analogues with benzoyl hydrazines

To research on the structure-activity relationships of our designed neonicotinoid compounds, a series of novel cis-configuration nitenpyram analogues with benzoyl hydrazines were designed and synthesized. The structures of all compounds were confirmed by IR, 1H NMR, MS, and elemental analysis. Preliminary bioassays indicated that all the analogues exhibited good insecticidal activities against Nilaparvata legen and Aphis medicagini at 500mgL-1.
