An efficient and green one-pot multi component microwave synthesis of diethyl 1-(4-aryl)-4-phenyl-1H-pyrrole-2,3-dicarboxylates has been accomplished under solvent-free conditions from the reaction of benzaldehyde, diethyl acetylenedicarboxylate and nitroalkane with various amines. The merit of the methodology is that the interlamellar structure of the montmorillonite K-10 favoured the reaction in synthesizing the tetra substituted pyrroles with the environmentally benign reaction conditions by offering good product yields.
