synthesis of 3-haloimidazopyridine derivatives has developed by the halogenation of imidazoheterocycles with BuNX (X = Cl, Br, and I) using iodobenzene diacetate as oxidant in ethanol. This protocol features with short reaction time for bromination and iodination, ambient temperature, facile operation, good functional group tolerance and good yeilds.
以二乙酸碘苯为氧化剂,通过 BuNX(X = Cl、Br 和 I)对咪唑杂环进行卤化,开发了一种高效、环保的 3-卤代咪唑并吡啶衍生物合成方法。该方案具有溴化和碘化反应时间短、环境温度低、操作简便、官能团耐受性好、收率好的特点。
