为了寻找具有较高活性的杂环农药, 通过5-取代苯基-2-呋喃甲酰氯与取代吡唑肟的缩合反应, 制备了一系列含多取代基呋喃环结构的吡唑肟酯类化合物. 利用1H NMR, 13C NMR和元素分析对目标化合物的结构进行了表征. 初步的生物试验结果表明, 某些化合物表现出一定的杀虫或杀螨活性. 其中, 5-(4-三氟甲基苯基)呋喃-2-甲酸-[1-甲基-3-甲基-5-(2,4-二氯苯氧基)吡唑-4-甲醛]肟酯(6g)在浓度为400 μg/mL时对朱砂叶螨的杀死率达到83%; 5-(4-氟苯基)呋喃-2-甲酸-[1-(4-甲基苯基)-3-甲基-5-(4-甲基苯氧基)吡唑-4-甲醛]肟酯(6m)在浓度为400 μg/mL时对小菜蛾和蚜虫表现的杀死率分别为71%和64%.

In search of novel heterocyclic compounds with potent biological activities, a series of novel pyrazole oxime ester derivatives bearing substituted furan ring were prepared by the reaction of 5-substituted phenyl-2-furan carbonyl chloride with different pyrazole oximes. The structures of the target compounds were characterized by 1H NMR, 13C NMR and elemental analysis. The bioassay data exhibited that some title compounds showed certain acaricidal or insecticidal activities. For example, 5-(4-trifluoromethylphenyl)furan-2-formic acid-[1-methyl-3-methyl-5-(2,4-dichlorophenoxy)pyrazole-4-carbaldehyde]-oxime ester (6g) displayed 83% inhibition rate against Tetranychus cinnabarinus at the concentration of 400 μg/mL, and 5-(4-fluoro-phenyl)furan-2-formic acid-[1-(4-methylphenyl)-3-methyl-5-(4-methylphenoxy)pyrazole-4-carbaldehyde]oxime ester (6m) showed insecticidal activity against Plutella xylostella and Aphis craccivora with 71% and 64% mortality, respectively, at the same concentration.
