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
