Acetyl-CoA carboxylase (ACCase, EC 6.4.1.2) was one of important herbicidal targets. However, the number of resistant weeds targeting to ACCase had risen to the third place among all of herbicidal targets. Therefore, it is of great importance to design new ACCase inhibitors. Herein, based on the crystal structures, aryloxyphenoxypropanotes (APP)-site and cyclohexanedioneoximes (CHD)-site were used to constructing APP+CHD-site, and then thirteen compounds were designed and synthesized. All the newly prepared compounds were characterized by 1H NMR, 13C NMR and HRMS. The molecular docking showed that 2-((4-(2,4-dichlorophenoxy)phenoxy)methyl)-5-(2-(ethylthio)propyl)cyclohexane-1,3-dione (10a) could occupy not only APP-site, but also CHD-site. In addition, based on the herbicidal activity, some compounds showed some inhibition rate upon tested weeds. Most importantly, 5-(2-(ethylthio)propyl)-2-((4-phenoxyphenoxy)methyl)cyclohexane-1,3-dione (10b) showed a wide range of herbicidal spectrum, which could be used to inhibit not only poaceae weeds, but also broadleaf weeds. All these results indicated that this type of compounds worth of the further investigation.
