Optical activity 1,5-substituted-1,3,5-hexahydrotriazine-2-N-nitroimines: Synthesis and insecticidal activity

Twelve novel neonicotinoid analogues 1-(2-furfuryl)-5-substituted-1,3,5-hexahydrotriazine-2-N-nitroimines 3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i, 3j, 3k, 3l were synthesized. Their structures were characterized by 1H NMR, IR, and elemental analysis. The preliminary bioassay tests showed that all the title compounds gave 90% mortality against Nilaparvata lugen 500 mg/L.
