为了发现具有除草活性的新型分子结构, 以苯酚为原料, 设计合成了13个未见文献报道的新化合物(E)-7-(4,6-二甲氧基嘧啶-2-氧基)-2,3-二氢-1H-茚-O-取代-1-酮肟醚类化合物. 化合物的结构通过1H NMR, MS, 元素分析进行了表征确证, 其中目标物6h进一步通过了单晶衍射. 初步生物活性测试结果表明, 在试验浓度下部分化合物显示有一定的除草活性, 其中化合物6i和6l对测试杂草表现出20%～40%的抑制活性.

The purpose of the study was looking for the novel compounds with herbicidal activities. Thirteen novel (E)-7-(4,6-dimethoxypyrimidin-2-yloxy)-2,3-dihydro-1H-inden-O-substituted-1-ketoximes were designed and synthesized using phenol as starting material. The structures of synthesized compounds were confirmed by 1H NMR, MS, elemental analysis. And the structure of the target 6h was confirmed further by X-ray techniques. The preliminary bioassay showed that some of them exhibited certain herbicidal activities, for example, the inhibition rates of compounds 6i and 6l were 20%～40% against Echinochloa crusgalli, Digiatra sanguinalis, Setaria viridis, Brassica juncea, Amaranthus retroflexus and Chenopodium album at 150 g/hm2.

Key words: pyrimidinylsalicylic acid, indenone, synthesis, herbicidal activity
