α-Hydroxyl amides are important skeleton and valuable intermediates that present in many natural products, pharmaceutical active compounds, and organic functional materials. The main methods for synthesis of α-hydroxyl amides are either through amidation of α-hydroxyl acids, or by reduction of α-keto amides. Herein, a convenient potassium hydroxide/dimethyl sulfoxide promoted aerobic oxidation reaction to prepare N-substituted α-hydroxyl phenylacetamides is reported in good to high yields. 21 corresponding products were obtained and characterized by 1H NMR, 13C NMR and HRMS. The molecular structure of 2-(2-bromophenyl)-2-hydroxy-N-(p-tolyl)acetamide (2a) was confirmed by using single-crystal X-ray analyses.

Key words: α-hydroxyl amides, aerobic oxidation, synthesis, KOH-DMSO
