A new base metal catalyzed sustainable multicomponent synthesis of pyrroles from readily available substrates is reported. The developed protocol utilizes an air‐ and moisture‐stable catalyst system and enables the replacement of themutagenic α‐haloketones with readily abundant 1,2‐diols. Moreover, the presented method is catalytic in base and the sole byproducts of this transformation are water and
报道了一种新的贱金属催化的从易获得的底物上吡咯的可持续多组分合成。所开发的方案利用了空气和水分稳定的催化剂体系,并能够用容易产生的1,2-二醇代替易诱变的α-卤代酮。而且,所提出的方法在碱中是催化性的,并且该转化的唯一副产物是水和氢气。实验和计算机理研究表明,该反应通过组合的无受体脱氢氢自动转移方法进行。
