A series of novel 6,7,8,9-tetrahydro-2-(2-aryloxypyrimidin-4-yl)-2H-[1,2,4]triazolo[4,3-a]azepin-3(5H)-ones were designed and efficiently synthesized. Their structures were determined by IR, 13C and 1H NMR, mass spectroscopy, and elemental analysis. These compounds were screened for herbicidal activities against rape and barnyard grass. Compounds 5a-5f and 5m exhibited moderate herbicidal activity
一系列新颖的6,7,8,9-四氢-2-(2-芳氧基嘧啶-4-基)-2 H- [1,2,4]三唑[4,3 - a ] azepin-3(5 H)-被设计并有效地合成。通过IR,13 C和1 H NMR,质谱和元素分析确定其结构。筛选了这些化合物对油菜和n草的除草活性。化合物5a-5f和5m对油菜表现出中等的除草活性。另外,研究了中间体1-(氮杂-2-亚甲基)-2-(2-氯嘧啶-4-基)-肼(3)的合成,并讨论了初始步骤收率低的原因。出色地。
