Sulfinamides have widespread applications in organic synthesis, especially for the preparation of S(VI) derivatives such as sulfonimidamide and sulfonimidate ester. The previous methods for the preparation of these compounds are restricted to an aryl substituent or Grignard reagent with limited functional groups. Here, we disclosed a photocatalyzed approach for obtaining these compounds with high functionalization
亚磺酰胺在有机合成中有着广泛的应用,特别是用于制备磺酰亚胺和磺酰亚胺酯等S(VI)衍生物。以前制备这些化合物的方法仅限于芳基取代基或具有有限官能团的格氏试剂。在这里,我们公开了一种获得这些具有高官能化水平的化合物的光催化方法。易于获得的 1,4-二氢吡啶,可提供以 C sp 3为中心的烷基自由基,与易于获得的N顺利反应-亚磺酰胺以良好的产率生产相应的亚磺酰胺。此外,通过在一锅中连续添加卤素试剂和N-或O-中心的亲核试剂,可以将产生的亚磺酰胺转化为相应的磺酰亚胺和磺酰亚胺酯。该方法不仅可以实现克级亚磺胺类药物的制备,而且保证了一系列药物或天然产物的后修饰。
