An operationally simple and mild one-pot protocol for the synthesis of a variety of 3,5-diarylpyridines from β-nitrostyrenes was achieved by using elemental iron. This reaction proceeds via reduction of the nitro group, resulting in in situ imine formation followed by trimolecular condensation with concomitant debenzylative aromatization. By employing this method, a series of symmetrical and unsymmetrical
通过使用元素铁实现了一种从β-硝基苯乙烯合成各种3,5-二芳基吡啶的操作简单且温和的一锅操作方案。该反应通过硝基的还原进行,导致原位亚胺形成,随后三分子缩合并伴随脱苄基芳构化。通过采用这种方法,合成了一系列对称和不对称的3,5-二芳基吡啶,收率良好至极佳。此外,该方法还用于合成克级的消炎药Sch-21418。
