| 摘要 |
The present invention relates to a method for synthesising a phenanthrene compound as shown in formula (I) in a potassium tert-butoxide environment, the method comprising: reacting the compound of formula (II) with the compound of formula (III) in an inert atmosphere, in the presence of a catalyst, organic ligands and potassium tert-butoxide, and in a solvent, thereby obtaining the compound of formula (I), wherein R1 and R2 are each independently H, a C1-C6 alkyl group, a C1-C6 alkoxy group or a halogen, R3 is a C6-C10 aryl group or a C5-C8 heteroaryl group, the C6-C10 aryl group or the C5-C8 heteroaryl group being optionally substituted by 1-3 substituents, the substituents being C1-C6 alkyl groups or halogens. The method obtains a good effect via the selection of an appropriate catalyst, organic ligands, base and solvent, and has wide prospects for industrial application. |
