摘 要:A series of novel tetrahydroimidazo[1,2-a]pyridine-5(1H)-one derivatives containing a electronegative pharmacophore(=CNO_2) were synthesized via practical aza-ene reaction and characterized by ~1H NMR,^(13)C NMR,^(19)F NMR and HRMS. Preliminary bioassays showed that some of the target compounds exhibited good insecticidal activity against brown planthopper(Nilaparvata lugens) and cowpea aphids(Aphis craccivora) at 500 mg L^(-1). Among them, compound 11 h was active against brown planthopper at100 mg L^(-1). The insecticidal activities varied significantly depending on the types and patterns of the substituents, which provided guidance for further investigation on structure modifications.
