Synthesis and Fungicidal Activity of 1-(4-Chlorobenzoyl)-3-[5-(4-pyridyl)-1,3,4-thiadiazol-2-yl]urea
【摘要】 通过2-氨基-5-(4-吡啶基)-1,3,4-噻二唑与4-氯苯甲酰基异氰酸酯反应,合成了目标化合物1-(4-氯苯甲酰基)-3-[5-(4-吡啶基)-1,3,4-噻二唑-2-基]脲,通过IR1、H NMR、MS和元素分析等方法对它的结构进行了表征.并测定了其杀菌活性,结果发现:目标化合物在50 mg/L浓度下对黄瓜灰霉病菌和苹果轮纹病菌的抑制率达到80%以上.
【Abstract】 The title compound 1-(4-chlorobenzoyl)-3-[5-(4-pyridyl)-1,3,4-thiadiazol-2-yl]urea has been synthesized by the reaction of 2-amino-5-(4-pyridyl)-1,3,4-thiadiazole with 4-chlorobenzoyl isocyanate,and its structure was characterized by IR,~1H NMR,MS and elemental analysis.The results of biological test showed that the title compound exhibited relatively good fungicidal activity,which could reach above 80% against Botrytis cinerepers and Dothiorellagregaria at the dosage of 50 mg/L(mass fraction).
