含氮分子在烯烃侧链上的分子内环化是构建 N-杂环的有效策略,这在药物和材料等领域至关重要。然而,对于氮结构单元(包括以 N 为中心的自由基)来说,类似的分子间环化反应较少,并且尚未建立发散和模块化版本。在这里,我们报道了使用硫亚胺作为双功能N-自由基前体与烯烃进行环化反应,通过光氧化还原催化一步生成N-未保护的杂环。结构多样的硫亚胺可以一步合成,然后与烯烃结合,得到具有合成价值的五元、六元和七元杂环。通过试剂的双功能特性实现的自由基-极性交叉环化可以实现广泛而多样化的范围,这与所有其他基于 N 中心自由基的反应不同。与目前其他单一环化方法相比,硫亚胺的模块化合成允许 N-杂环产物具有更大的结构多样性。
