In this study, in order to find novel biologically active pyrazole oxime compounds, a number of dichloro-allyloxy-phenol-containing pyrazole oximes were designed and synthesized according to the method of active group combination. All of the target compounds were confirmed by 1H-NMR, 13C-NMR and elemental analysis. In addition, bioassays showed that all of the newly synthesized compounds had no acaricidal activity against Tetranychus cinnabarinus and low insecticidal activity against Aphis craccivora at tested concentrations. However, most of them displayed excellent insecticidal activity against Oriental armyworm at a concentration of 500 μg/mL, and some designed compounds still exhibited potent insecticidal activity against Oriental armyworm even at the dose of 20 μg/mL, especially compounds 7f, 7n and 7p had 100%, 90% and 90% inhibition rates, respectively, which were comparable to that of the control pyridalyl.
在本研究中,为了寻找新型生物活性吡唑肟化合物,根据活性基团组合的方法设计并合成了多种含有二氯烯丙氧基苯酚的吡唑肟类化合物。所有目标化合物均通过1H-NMR、13C-NMR和元素分析得到确认。此外,生物测定显示,所有新合成的化合物对朱砂叶螨无杀螨活性,对豌豆蚜的杀虫活性较低(测试浓度下)。然而,它们大多数在500 μg/mL浓度下对东方粘虫显示出优异的杀虫活性,其中某些设计化合物甚至在20 μg/mL剂量下仍对东方粘虫表现出强效的杀虫活性,特别是化合物7f、7n和7p分别达到了100%、90%和90%的抑制率,这些结果与对照化合物pyridalyl相媲美。
