Fourteen title compounds, 1-substituted-5-substitutedphenylthio-4-pyrazolaldoxime ester derivatives 4a-4n, were synthesized from the starting material 1-substitutedphenyl-3-methyl-5-substitutedphenylthio-4-pyrazolaldoximes 3 by treatment with acyl chloride. The synthesized compounds were characterized by physical constants, and the structures of the title compounds were further confirmed by IR, 1H
通过用酰氯处理,由起始原料1-取代苯基-3-甲基-5-取代苯硫基-4-吡唑醛肟3合成14个标题化合物,即1-取代-5-取代苯硫基-4-吡唑并肟肟酯衍生物4a-4n。通过物理常数表征合成的化合物,并通过IR,1 H NMR,13 C NMR和元素分析进一步证实标题化合物的结构。生物测定结果表明标题化合物具有弱到良好的抗TMV生物活性,其中4l具有对TMV CP的高亲和力,显着增强了烟叶的抗病性。
