【摘要】 以莰烯衍生物内型异莰烷基甲醛与氨基硫脲衍生物进行缩合反应，合成了5种缩氨基硫脲类化合物（3a～3e）,并通过IR、MS、¹H NMR和¹³C NMR等分析方法对其结构进行了表征。采用菌丝生长速率法测试了化合物3a～3e对水稻纹枯病菌等8种植物病原菌的生长抑制作用，结果表明：5种化合物中，内型异莰烷基甲醛缩氨基硫脲（3a）对8种植物病原菌的抑制率最高，在质量浓度为50 mg/L时，3a对油茶炭疽病菌、枇杷炭疽病菌的抑制率分别为91.9%和97.2%,对油茶果生刺盘孢菌和彩绒革盖菌的抑制率均达100%,对水稻纹枯病菌、松枯梢病病原菌和西瓜枯萎病菌的抑制率分别为80.7%、 79.8%、 79.5%,均优于阳性对照样百菌清。更多还原

【Abstract】 5 endo-isocamphanyl-formaldehyole thiosemicarbazide compounds（3a-3e） were synthesized by condensation reactions of camphene derivatives endo-isocamphanyl-formaldehyole with thiosemicarbazide derivatives. Their structures were characterized by IR, MS, ¹H NMR and ¹³C NMR. The mycelial growth rate method was used to study the inhibition effects of the related compounds on the growth of 8 plant pathogenic fungi including Rhizoctonia solani. The results showed that, among 5 compounds, the inhibition rate of endo-isocamphanyl-formaldehyole thiosemicarbazide（3a） was the highest against 8 plant pathogenic fungi. At the mass concentration of 50 mg/L, the inhibition rates of 3a against Colletotrichum gloeosporioides and Colletotrichum acutatum were 91.9% and 97.2%, respectively. The inhibition rates of 3a against Colletotrichum fructicola and Coriolus versicolor were both 100%. The inhibition rates of 3a against Rhizoctonia solani, Sphaeropsis sapinea and Fusariumoxyporum f. sp. niveum were 80.7%, 79.8% and 79.5%, respectively, which were better than that of the positive control sample of Chlorothalonil.更多还原
