tolerance, provides a direct and atom-economic approach for the synthesis of valuable β-amino sulfone derivatives as a single regioisomer. In addition to terminal alkenes, internal alkenes participate in this reaction with high diastereoselectivity. N-Sulfonyl ketimines with aryl or alkyl substituents were found to be compatible with this reaction condition. This method could be applied in the late-stage
通过使用现成的N-磺酰基酮亚胺作为双功能试剂,开发了烯烃的有机光催化磺酰化。这种转化具有显着的官能团耐受性,为合成有价值的 β-氨基砜衍生物作为单一区域异构体提供了一种直接且原子经济的方法。除了末端烯烃外,内部烯烃也以高非对映选择性参与该反应。发现具有芳基或烷基取代基的N-磺酰基酮亚胺与该反应条件相容。该方法可应用于药物的后期修饰。此外,观察到烯烃正式插入环状磺酰亚胺中,得到扩环产物。
