| titleOfInvention | A kind of preparation method of benzoxazole derivative |
| abstract | The invention discloses a preparation method of o-benzophenone benzoxazole derivatives. In an organic solvent, a palladium phosphine complex and norbornene catalyze halogenated benzene with substituted benzoic anhydride and substituted Benzoxazole reaction, one-pot synthesis of o-benzophenone benzoxazole derivatives. The reaction raw materials of halogenated benzene, substituted benzoic anhydride and substituted benzoxazole used in the preparation method of the invention are cheap and easy to obtain, the synthesis method is simple, and the cost can be greatly reduced by using a small amount of metal palladium as a catalyst. The method of the invention can be used for synthesizing a series of o-benzophenone benzoxazole derivatives, and the synthesized products can be applied to the fields of medicine, spices, dyes and the like, and have wide applications. |
