摘要
为寻找新型结构的农药先导化合物,采用2-甲硫基-1-取代苯基乙酮与取代苯甲酰肼反应合成了11个2-甲硫基-1-苯基乙酮苯甲酰腙类化合物,其化学结构经质谱、1H核磁共振与元素分析确证。生物活性试验结果表明,部分化合物具有杀菌或杀虫活性,如2-甲硫基-1-(4-甲基苯基)乙酮-4-氯苯甲酰腙( j)在500mg/L时对黄瓜灰霉病菌B.cinerea、小麦赤霉病菌G.zeae具有良好的杀菌活性,其抑制率达到95%以上。
In search of pesticide lead compound with new structure type, eleven novel (2-methylthio)-1-phenylethanone benzoylhydrazones were designed and synthesized by reacting (2-methylthio) substituted acetophenone with substituted benzoylhydrazones. Their structures were confirmed by MS, ()~1H NMR and elemental analysis. The preliminary bioassay showed that some of title compounds had fungicidal activities or insecticidal activities, for example, (2-methylthio)-1-(4-methylphenyl)ethanone 4-chloro-benzoylhydrazone exhibited more than 95% (inhibition) against Botrytis cinerea and Gibberella zeae at 500 mg/L.
