Synthesis, Crystal Structure and Insecticidal Activity of the Optical Active Neonicotinoid Analogues

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, whi...

Description
Summary: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）.
