1,2-arylboration of alkenyl amines bearing a cleavable picolinamide directing group. With aryl halides as electrophiles and B2Pin2 as nucleophiles, a wide range of alkenes could be converted into valuable boryl-functionalized aliphatic amines. The reaction proceeds with high levels of chemo- and regiocontrol and exhibits high functional group tolerance. In addition, the pinacol boronic ester group
我们在此报告了一种三组分 1,2-arylboration 的烯基胺,带有可裂解的
吡啶酰胺导向基团。使用芳基卤化物作为亲电子试剂和 B 2 Pin 2作为亲核试剂,多种烯烃可以转化为有价值的
硼基官能化脂肪胺。该反应以高
水平的
化学和区域控制进行,并表现出高官能团耐受性。此外,
频哪醇硼酸酯基团可以进行各种转化,表明该协议可能为烯基胺的多功能区域选择性双功能化提供一个平台。
