摘　　要：以5种苄氧基/烷氧基苯胺为基础,设计合成了系列新颖的N-苄氧/烷氧苯基-4,6-二取代嘧啶胺类化合物,其结构经1H NMR、MS及元素分析确证,其中化合物5r的单晶结构经X射线单晶衍射分析确证.油菜平皿法和稗草小杯法测试除草活性结果表明,4种苄氧基/烷氧基苯胺3a,3b,3d,3e具有较好的除草活性,在100μg/mL浓度下对单子叶稗草生长抑制率可达到77.3%~88.5%.KARI活性测试结果表明,化合物5a^5s有较弱的KARI抑制活性.On the basis of the structures of five 4-benzyloxy/alkyloxy-anilines, 19 N-（4-benzyloxy/alkyloxyphenyl） - （4,6-disubstituted-pyrimidin-2-yl） -amine derivatives were designed and synthesized. The structures of all the compounds were characterized by ^1H NMR, MS and elemental analyses. The single crystal structure of compound 5r was determined to further elucidate the structure. The herbicidal activity of the title compounds was evaluated through barnyardgrass cup, rape root methods and KARI test. Herbicidal assay indicate that substituted-anilines 3a, 3b, 3d, 3e exhibited good growth inhibitory activities against barnyardgrass, which are 88.5% , 77.3%, 82. 4%, and 80. 2%, respectively at the mass concentration of 100 ug/mL. The KARI test of compounds 5a-5s show that the compounds have a weak inhibitory effect on KARI enzyme.
