Eight novelneonicotinoids N‐oxide analogues were designed and synthesized. All the compounds have been identified by 1H NMR and HRMS. The N‐oxide analogues exhibit high insecticidal activity against cowpea aphids (Aphis craccivora) at 250 mg·L−1. The influence of N‐oxide formation on the biological activity was elucidated by computational chemical study, and it indicated that the water bridge hydrogen
设计并合成了八种新的烟碱类N-氧化物类似物。所有化合物均已通过1 H NMR和HRMS鉴定。所述Ñ氧化物类似物表现出抗蚜虫豇豆高杀虫活性(豆蚜在250毫克)·L -1。通过计算化学研究阐明了N氧化物形成对生物活性的影响,表明水桥氢键网络由于与吡啶环相连的O原子的作用而断裂。
