| titleOfInvention | Preparation method of 5-maleimide chromone compound |
| abstract | The invention discloses a preparation method of 5-maleimide chromone compounds, which comprises the following steps: in DCE solvent with [ Ru (p-cymene) Cl 2 ] 2 And AgNTf 2 As a catalyst, silver acetate as an additive, toThe maleimide compound and the chromone compound are taken as substrates to synthesize the 5-maleimide chromone compound. The method has the advantages of cheap and easily-obtained reaction raw materials, simple preparation method, low reaction cost, short reaction time, high yield and simple operation by using ruthenium as a catalyst, and is suitable for synthesizing different types of 5-maleimide chromone compounds. The method can be used for synthesizing a series of 5-maleimide chromone compounds, and the synthesized product can be used as an intermediate compound for further constructing complex active compounds; meanwhile, the compounds have great medicinal activity potential. |
