摘要
利用天然来源的芳烃卤化物与反式-4-羟基- l -脯氨酸进行串联一锅交叉偶联反应，建立了一种简便、新颖的纳米氧化铜催化合成n -芳基吡咯的途径。这种方法是配体自由条件的第一份报告，是一种可持续的资源，通过挤压和氧化还原胺化。使用的催化剂可以回收和循环利用多达五次，具有高效的活性。
Recyclable Copper Oxide Catalyzed Synthesis of N -Arylpyrroles from Arylhalides and Trans-4-Hydroxy-L-Proline
A facile and novel copper oxide nanoparticle catalyzed route has been developed for the synthesis of N-arylpyrroles, through tandem one-pot cross-coupling reaction of aryl halides and trans-4-hydroxy-L-proline, which is procured from natural source. This methodology is a first report of ligand free conditions and is a sustainable resource, via extrusion followed by redox amination. Catalyst used can be recovered and recycled up to five cycles with efficient activity.
