Eight novel neonicotinoid analogues 1-（2-tetrahydrofurfuryl）-5-substituted-1,3,5-hexahydrotriazine-2-N-nitroimines 3a-3h were synthesized, and their structures were characterized by ^1H NMR, IR and elemental analysi...Eight novel neonicotinoid analogues 1-（2-tetrahydrofurfuryl）-5-substituted-1,3,5-hexahydrotriazine-2-N-nitroimines 3a-3h were synthesized, and their structures were characterized by ^1H NMR, IR and elemental analysis. The stereostructure of 3a was determined by the single-crystal X-ray analysis, which exhibits a half-chair conformation and dihedral angle is 49.70°. The preliminary bioassay tests showed that all the title compounds exhibited good insecticide activities against Nilaparvata legen （N. legen）.展开更多
A new series of 1,3,5-trisubstituted-l,3,5-hexahydrotriazine-2-N-nitroimines （3a--3j） were designed and synthesized as novel neonicotinoid analogues, and their structures were characterized by 1H NMR, IR, elemental ...A new series of 1,3,5-trisubstituted-l,3,5-hexahydrotriazine-2-N-nitroimines （3a--3j） were designed and synthesized as novel neonicotinoid analogues, and their structures were characterized by 1H NMR, IR, elemental analysis and MS. The preliminary bioassay tests showed that most of the target compounds had good insecticidal activities against Nilaparvata lugens as well as Aphis medicaginis at 500 mg/L, while compound 3i had 100% mortality against Nilaparvata lugens at 20 mg/L.展开更多
