Pyrroles are an important class of heterocyclic compounds. The pyrrole subunit occurs in a number of pharmacologically active natural products and synthetic drugs. [1] They have also found application in the field of material science. [2] Although many methods have been reported for the synthesis of pyrroles, [3] the pursuit for the more general, convenient and efficient generation continues to be an area of intensive research. [4] Herein we report that the copper-catalyzed ...
