N‐nitrourea derivatives bearing various aryl substituents were conveniently obtained via three steps including nitration, carbamic chlorination, and aminolysis reactions. The structures of all newly synthesized compounds were characterized and confirmed by IR, 1H‐NMR, MS, and elemental analysis. The preliminary bioassays indicate that five compounds possess sufficient fungicidal activity against Rhizoctonia
可以通过三个步骤方便地获得一系列带有各种芳基取代基的N-硝基脲衍生物,包括硝化,氨基甲酸氯化和氨基分解反应。通过IR,1 H-NMR,MS和元素分析对所有新合成化合物的结构进行了表征和确认。初步的生物分析表明,五种化合物具有足够的抗茄枯萎病菌的杀真菌活性。还根据实验数据讨论了结构-活性关系(SAR),并使用比较分子场分析(CoMFA)和比较分子相似性指数分析(CoMSIA)分析了进一步的定量结构-活性关系(QSAR)。
