    Project supported by the National Basic Research Program of China (973 Program, No. 2010CB126100), the National High Technology Research and Development Program of China (863 Program, No. 2011AA10A207), the National Key Technology R&D Program of China (No. 2011BAE06B01) and the National Natural Science Foundation of China (No. 21272071).

Six novel neonicotinoid analogues with bicyclic ring system were designed and synthesized, and their structures were characterized by 1H NMR, 13C NMR, HRMS and single crystal X-ray diffraction analysis. Preliminary bioassays showed that five target compounds 6a, 6c6f exhibited good insecticidal activities against cowpea aphids (Aphis craccivora) at 500 mg·L-1. Docking study was applied to investigate the effect of the bicyclic ring system of the target compound 6a on the biological activity, and compared with mode of action of imidacloprid (IMI) and compound 6a. It was found that the only π-π stacking interaction was found between the plane of pyridine of the target compounds 6a and the aromatic side chain of Tyr 147, which was different binding mode with that of IMI.
