Abstract: By using 2,3-epoxypropan-1-ones and arylamine, boron trifluoride acetic acid complex/acetylacetone-promoted in situ ring opening-aryl migration reaction at 80 ℃ was developed in 1,4-dioxane, synthesizing a series of N-aryl enaminones in good yields. The structures of all products were characterized by 1H NMR, HRMS and IR spectra. In addition, the structure of compound 3 was further confirmed by single-crystal X-ray diffraction analysis.

Key words: 2,3-epoxypropan-1-one, arylamine, enaminone
