A straightforward acylaltion of pyridine derivatives has been developed using K2S2O8 as the oxidant and water as a green solvent. The corresponding 2-acylpyridines were synthesized with high chemo- and regioselectivity in good to high yields. This efficient and practical method could serve as a new tool for the convenient synthesis of 2-benzoylpyridines of interest for future pharmaceutical and chemical
使用K 2 S 2 O 8作为氧化剂和水作为绿色溶剂,开发了吡啶衍生物的直接酰基化方法。以高至高产率合成具有高化学和区域选择性的相应的2-酰基吡啶。这种有效和实用的方法可以用作方便地合成感兴趣的2-苯甲酰基吡啶的新工具,以用于未来的药物和化学应用。
