novel pyrazolyl acrylonitrile derivatives was designed, targeting Tetranychus cinnabarinus, and synthesized. Their structures were identified by combination of 1H NMR, 13C NMR, and MS spectra. The structures of compounds 18 and 19 were further confirmed by X-ray diffraction. Extensive greenhouse bioassays indicated that compound 19 exhibits excellent acaricidal activity against all developmental stages
设计并合成了一系列新颖的吡唑基丙烯腈衍生物,并以朱砂叶螨(Tetranychus cinnabarinus)为靶标。它们的结构通过1 H NMR,13 C NMR和MS光谱的组合来鉴定。化合物18和19的结构通过X射线衍射进一步证实。大量的温室生物测定表明,化合物19对朱砂毛虫的所有发育阶段均表现出优异的杀螨活性,优于商品化的嘧菌草醚和螺二氯芬。结果表明,化合物19的急性毒性对哺乳动物来说是相当低的。还讨论了结构与活动之间的关系。
