Summary: | Thirteen novel N-(2-fluoro-5-(3-methyl-2,6-dioxo-4-(trifluoromethy)-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 IH NMR, IR, mass spectrum and elemental analyses. Subsequently, the herbicidal activities of the as-prepared compounds were evalu-ated in the greenhouse. Bioassay results indicated that most of compounds had better herbicidal activities against dicotyledonous weeds. Among all the tested compounds, compounds 4a--4i showed good herbicidal activities at both pre-emergence and post-emergence treatment against two or three kinds of dicotyledonous weeds, such as Abutilon theophrasti Medic, Amaranthus ascendens L, and Chenopodium album L at the dosage of 75 g ai/ha. |
