| 摘 要： | 为考察脂肪环的大小对噻二唑啉衍生物杀菌活性的影响,以环己酮为原料,先与取代缩氨基硫脲缩合,得N-取代环己酮缩氨基硫脲,再经二氧化锰氧化关环,得到9个未见文献报道的标题化合物,所有化合物的结构均经过IR、13C NMR和元素分析确证。初步杀菌实验结果表明,所有目标化合物在100 mg/L和50 mg/L浓度下,对棉花立枯病菌Rhizoctonia solani Kühn和棉花枯萎病菌Veticillium dahlide具有一定的杀菌活性,特别是对棉花立枯病菌,在50 mg/L下有5个化合物的抑制率达90％以上。

| Abstract: | Nine new title compounds, 2-(1,5-pentamethylene)-5-substituted imino-Δ3-1,3,4-thiadiazoline were synthesized from cyclohexanone via N-substituted cyclohexanone thiosemicarbazones,followed by oxidative cyclisation on treatment with manganese dioxide. The structure of all the compounds were confirmed by IR,13C NMR and elemental analysis. Preliminary bioassays showed that all the compounds had some fungicidal activity to Rhizoctonia solani Kühn and Veticillium dahlide at the concentration of 100 mg/L and 50 mg/L. The inhibition rate to R.solani reached 90% for five compounds at the concentration of 50 mg/L. |
