Paragraph 0013; 0015-0017, (2018/04/01)
The invention provides a preparation method of 2-substituted aryl oxazole. 2-substituted aryl oxazole compounds are prepared from phenol compounds and aldoxime ester compounds through a reaction. Thecorresponding 2-substituted aryl oxazole compounds can be prepared from the phenol compounds and the aldoxime esters by reacting in an organic solvent with catalysis of iron under mild conditions. Themethod has the advantages that reagents are economical and easily available, the application range of substrates is wide, the reaction conditions are mild, the operation is simple and the like.

An iron-catalyzed oxidative coupling/cyclization reaction for the synthesis of benzoxazoles at room temperature is reported. This reaction was enabled by an inexpensive iron(iii) catalyst by treating readily available phenol derivatives with benzoyl aldehyde oximes. Mechanistic studies show that benzoyl aldehyde oxime is not only used as a substrate, but also serves as an ancillary ligand to support the iron salt in the promotion of the transformation.
