A simple, rapid, efficient, and environmentally benign procedure for synthesis of polysubsfituted pyrroles has been achieved by the three-component reaction of amines, phenacyl bromide and dialkyl acetylenedicarboxylates under solvent free conditions using nano structures of ZnO as catalyst. Different morphologies such as nanorods and nanosheets of catalysis have been synthesized by simple reflux method using sodium dodecylsulfate (SDS) and applied in this reaction. Nanorod ZnO catalyst exhibited a significant enhancement in the yield of the desired product. The catalyst exhibited remarkable reusable activity. (C) 2013 Elsevier B.V. All rights reserved.
