After addition to styrene, the generated benzylic radical could couple with a chiral L*CuIIAr complex to achieve enantioselective arylation. Various optical 2,2-diarylethylamines were efficiently synthesized from simple styrenes with high enantioselectivity, and these products can serve as valuable synthons toward bioactive molecules' synthesis.
我们使用新型 N-氟-N-烷基磺酰胺作为胺试剂,开发了一种铜催化的烯烃对映选择性分子间氨基芳基化,它可以与 Cu(I) 催化剂反应以释放相关的氨基自由基。添加到苯乙烯后,生成的苄基自由基可以与手性 L*CuIIAr 络合物偶联以实现对映选择性芳基化。各种光学 2,2-二芳基乙胺以高对映选择性由简单的苯乙烯有效合成,这些产物可作为有价值的合成子用于生物活性分子的合成。
