The synthesis of (4 or 5)-aryl-2-aroyl-1H-imidazoles and 2-hydroxy-3,6-diarylpyrazines from aryl methyl ketones via a cascade process of DMSO-HBr oxidation and Debus reaction was investigated. Owing to the simple starting materials, mild conditions, easy operation, high bioactivity of imidazole and pyrazine derivatives, this protocol has great potential in medicinal chemistry.
研究了由芳基甲基酮通过 DMSO-HBr 氧化和 Debus 反应的级联过程合成 (4 或 5)-芳基-2-芳酰基-1H-咪唑和 2-羟基-3,6-二芳基吡嗪。由于起始原料简单、条件温和、操作方便、咪唑和吡嗪衍生物的生物活性高,该方案在药物化学中具有很大的潜力。
