Here is reported the first example of an organocatalyzed coupling between pyrrole and isocyanates in a nanoconfined space. The hexameric resorcinarene capsule C is able to catalyze the direct coupling between isocyanates and pyrroles to give amidopyrroles with excellent yields and selectivities. The reaction catalyzed by C prevents the use of expensive and poorly atom-economical reagents. As in natural
在此报道了纳米受限空间中吡咯和异氰酸酯之间有机催化偶联的第一个例子。六聚间苯二甲烯胶囊C能够催化异氰酸酯和吡咯之间的直接偶联,从而以优异的产率和选择性得到酰胺吡咯。C催化的反应阻止使用昂贵且原子经济性差的试剂。与天然酶一样,C的空腔能够区分异构底物。
