A series of new N,N'-diacylhydrazine derivatives were designed and synthesized. Their structures were verified by 1H-NMR, MS and elemental analysis. The herbicidal activities and plant growth regulating activity of these N,N'-diacylhydrazines were evaluated. The herbicidal activity results showed that most of these N,N'-diacyl-hydrazines showed excellent in vivo activities against Echinochloa crus-galli, Digitaria sanguinalis, Brassica napus, Amaranthus retroflerus. Most of them exhibited higher herbicidal activities against dicotyledonous weeds than monocotyledonous weeds. To further investigate the structure-activity relationship, comparative molecular field analysis (CoMFA) was performed on the basis of herbicidal activity data. Both the steric and electronic field distributions of CoMFA are in good agreement in this work.
一系列新的N,N'-二酰肼衍生物被设计并合成出来。它们的结构通过1H-NMR、MS和元素分析得到了验证。这些N,N'-二酰肼的除草活性及植物生长调节活性被评估了。除草活性结果表明,这些N,N'-二酰肼对稗草、马唐、油菜和苋菜等杂草显示出了优异的体内活性。大多数化合物对双子叶杂草的除草活性高于单子叶杂草。为进一步研究结构与活性关系,在除草活性数据基础上进行了比较分子场分析(CoMFA)。在这项工作中,CoMFA的空间和电荷场分布均很好地吻合。
