| titleOfInvention | A kind of preparation method of oxazole derivatives |
| abstract | The invention discloses a preparation method of an oxazole derivative belonging to the technical field of organic synthesis. The method is as follows: adding substituted p-methylene quinone, substituted N-propargyl amide and indium trichloride into the reactor, adding solvent 1,2-dichloroethane, heating until the reaction is completed, rotating The filtrate was concentrated by an evaporator to obtain a crude product, which was separated by column chromatography to obtain the product. The synthetic method of the oxazole derivative provided by the invention is scientific and reasonable, the synthetic method is simple, the atom economy is high, and the product is easy to purify and the like. Its reaction equation is as follows: |
