含有桥接双环碳骨架的胺是药物化学的理想基石。在这里,我们报道了通过中间亚胺双自由基的光化学形式(4+2)环加成,二环[1.1.1]戊烷-1-胺转化为多种多取代的二环[3.1.1]庚烷-1-胺。据我们所知,这是首次报道将双环[1.1.1]戊烷骨架转化为双环[3.1.1]庚烷骨架的方法。水解亚胺产物得到复杂的,sp3丰富的伯胺构建块。
Amines containing bridged bicyclic carbon skeletons are desirable building blocks for medicinal chemistry. Herein, we report the conversion of bicyclo[1.1.1]pentan-1-amines to a wide range of poly-substituted bicyclo[3.1.1]heptan-1-amines through a photochemical, formal (4+2)-cycloaddition of an intermediate imine diradical. To our knowledge, this is the first reported method to convert the bicyclo[1.1.1]pentane skeleton to the bicyclo[3.1.1]heptane skeleton. Hydrolysis of the imine products gives complex, sp3-rich primary amine building blocks.
