A series of novel imidazo[4,5‐b]pyridine derivatives were designed and synthesized. The structures of all the newly synthesized compounds were identified by spectroscopic data NMR, MS, and elemental analysis. Bioassay showed that the compounds exhibited potent fungicidal activities against Erysiphe graminis, Puccinia polysora, and so forth. Particularly, 2‐chloro‐5‐((5‐methoxy‐2‐(2‐(trifluoromethy
设计并合成了一系列新型的咪唑并[4,5- b ]吡啶衍生物。通过光谱数据NMR,MS和元素分析鉴定所有新合成的化合物的结构。生物测定表明,该化合物显示出强的杀真菌活性抵抗禾白粉菌,隐匿柄polysora,等等。特别是,2-氯-5 - ((5-甲氧基-2-(2-(三氟甲基)苯基)-3- ħ -咪唑并[4,5- b ]吡啶-3-基)甲基)噻唑(图9b)显示杀真菌对P的效力。 多索拉。其EC 50值:4.00 mg / L与戊唑醇相当。讨论了目标化合物的结构活性关系。
