A practical one‐pot protocol for the synthesis of 2,5‐disubstituted oxazoles from 1‐aryl‐2‐nitroethanones was reported. In the presence of iron/AcOH in acetonitrile, the reaction of 1‐aryl‐2‐nitroethanones with trimethyl orthoacetate or trimethyl orthobenzoate delivered the corresponding 2,5‐disubstituted oxazoles in moderate to good yields.
据报道,有一个实用的一锅法从1-芳基-2-硝基乙酮合成2,5-二取代的恶唑。在乙腈中存在铁/ AcOH时,1-芳基-2-硝基乙酮与原乙酸三甲酯或原苯甲酸三甲酯的反应以中等至良好的产率生成了相应的2,5-二取代的恶唑。
