activate α-3° amines for deaminative arylation via condensation with an electron-rich aldehyde and merge this reactivity with nickel metallaphotoredox to generate benzylic quaternary centers, a common motif in pharmaceuticals and natural products. The reaction is accelerated by added ammonium salts. Evidence is provided in support of two roles for the additive: inhibition of nickel black formation and acceleration
我们报告了一种通过与富电子醛缩合来激活 α-3° 胺以进行脱
氨芳基化的方法,并将这种反应性与
镍金属光氧化还原结合以生成苄基季
铵中心,这是药物和
天然产物中的常见基序。加入
铵盐可加速反应。提供的证据支持添加剂的两个作用:抑制
镍黑形成和加速总反应速率。我们展示了广泛的胺和卤代
芳烃偶联伙伴,并展示了 ALK2
抑制剂的加速合成。
