| titleOfInvention | A kind of synthetic method of quinoxalinone compound |
| abstract | In the present invention, the chloroimine substrate is dissolved in a dichloroethane solution added with Na 2 CO 3 , and under the catalysis of palladium trifluoroacetate, the reaction is carried out in an oil bath for 6-20 h. According to the chloroimine substrate Different functional groups carry different reaction atmospheres under oil bath reaction conditions: when the chloroimine substrate is connected to a CO 2 Et group, the reaction atmosphere is argon, and when the chloroimine substrate is connected to an aryl group, The reaction atmosphere is air. After the reaction was completed, it was detected by thin layer chromatography (TLC), the reaction solution was quenched with saturated aqueous NH 4 Cl solution, extracted with ethyl acetate, dried over anhydrous Na 2 SO 4 , the solvent was removed, and the quinoxalinones were obtained by column chromatography compound. |
