Thirteen novel N‐(2‐fluoro‐5‐(3‐methyl‐2,6‐dioxo‐4‐(trifluoromethyl)‐2,3‐dihydropyrimidin‐1(6H)‐yl)phenyl)‐2‐phenoxy)acetamides were designed and synthesized utilizing 4‐fluoro‐aniline and ethyl 3‐amino‐4,4,4‐trifluoro‐but‐2‐enoate as starting materials. The chemical structures of all compounds were confirmed by 1H NMR, IR, mass spectrum and elemental analyses. Subsequently, the herbicidal activities
十三种新颖的N-(2-氟-5-(3-甲基-2,6-二氧代-4-(三氟甲基)-2,3-二氢嘧啶-1(6 H)-基)苯基)-2-苯氧基)乙酰胺以4-氟苯胺和3-氨基-4-3,4,4-三氟丁-2-烯酸乙酯为起始原料进行设计和合成。所有化合物的化学结构均通过1 H NMR,IR,质谱和元素分析确认。随后,在温室中评估了所制备化合物的除草活性。生物测定结果表明,大多数化合物对双子叶杂草具有更好的除草活性。在所有测试的化合物中,化合物4a – 4i在芽前和芽后处理中均以75 g ai / ha的剂量显示出对两种或三种双子叶杂草如除草剂Abutilon theophrasti Medic,Amaranthus ascendens L和Chenopodium album L的良好除草活性。
