Abstract

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
