Paragraph 0046-0052, (2021/06/21)
The invention discloses a synthesis method of a 2-aryl formyl benzoxazole compound, which comprises the following steps: in an oxygen-containing atmosphere and an ultrasonic environment, carrying out intramolecular cyclization-oxidation cascade reaction on N-(2-hydroxyphenyl)-2-aryl acetamide under the synergistic catalysis action of an acidic eutectic solvent and a cuprous salt, thereby obtaining the 2-aryl formyl benzoxazole compound. The method is mild in reaction condition, simple in step, green, energy-saving, high in reaction selectivity and product yield and excellent in substrate functional group compatibility, the acidic eutectic solvent/cuprous salt catalytic system can be recycled for multiple times, and the production cost is greatly reduced.
