agrochemical lead compounds due to its unique mode of action, novel chemical structure, and lack of reported resistance. To develop a new pyrimidinamine fungicide effective against cucumber downy mildew (CDM), a series of new pyrimidinamine derivatives containing an aryloxy pyridine moiety were designed and synthesized by employing the recently reported intermediate derivatization method (IDM). The structures
由于嘧啶胺的独特作用方式,新颖的化学结构和缺乏报道的抗药性,因此是发现农用化学先导化合物的理想模板。为了开发对黄瓜霜霉病(CDM)有效的新型嘧啶胺杀菌剂,通过使用最近报道的中间体衍生化方法(IDM)设计并合成了一系列含有芳氧基吡啶部分的新型嘧啶胺衍生物。所有化合物的结构均通过1 H NMR,元素分析,HRMS和X射线衍射鉴定。生物测定表明,某些标题化合物对CDM表现出优异的杀真菌活性。化合物9的活性最高(EC 50= 0.19 mg / L),明显优于市售杀菌剂diflumetorim,flumorph和cyazofamid。探索了合成的嘧啶胺的结构与杀菌活性之间的关系。研究表明,化合物9是有希望的杀真菌剂,可用于进一步开发。
