摘要
[目的]制备新型吡唑啉酮类化合物。[方法]以唑菌酯关键中间体3-(4-氯苯基)-1-甲基-1H-吡唑-5-醇为起始原料,经过羟醛缩合反应合成中间体4-(4-羟基-3-甲氧基苯亚甲基)-3-(4-氯苯基)-1-甲基-1H-吡唑-5(4H)-酮,再经亲核取代反应、酯化反应制备了11个新型吡唑啉酮类化合物。[结果]目标化合物的结构经过1H NMR进行了确证。[结论]室内生测结果表明该类化合物具有较好的杀菌和杀虫活性。
[Aims] The study aims to prepare novel pyrazolone compounds. [Methods] The intermediate of novel pyrazolone compounds 4-（4-hydroxy-3-methoxybenzylidene）-3-（4-chlorophenyl）-1-methyl-1H-pyrazol-5（4H）-one was synthesized from 3-（4-chlorophenyl）-l-methyl-lH-pyrazol-5-ol which was the key intermediate of pyraoxstrobin via aldol reaction. Followed by furthernucleophilic substitution and esterification to obtain eleven novel pyrazolone compounds. [Results] All compounds were confirmed by 1H NMR. [Conclusions] The indoor test results showed that most of compounds had good bactericidal and insecticidal activity.
