esters, readily derived from alkyl carboxylic acids, with benzophenone‐derived imines. Hydrolysis of the coupling products furnish alkylated primary amines. Primary, secondary, and tertiary alkyl groups can be transferred, and the coupling tolerates a diverse set of functional groups. The method allows rapid functionalization of natural products and drugs, and can be used to expedite syntheses of pharmaceuticals
烷基胺在药物和材料化学中是一类重要的有机化合物。到目前为止,很少有通过烷基亲核试剂与氮亲核试剂的金属催化交叉偶联反应来合成烷基胺的方法。这里描述的是一种采用串联光氧化还原和铜催化来实现烷基N交叉偶联的方法-羟基邻苯二甲酰亚胺酯,易于衍生自烷基羧酸,与二苯甲酮衍生的亚胺。偶联产物的水解提供了烷基化的伯胺。伯,仲和叔烷基可以转移,并且偶联可耐受各种官能团。该方法允许天然产物和药物的快速功能化,并且可用于加速从容易获得的化学原料中合成药物。
