variety of tetra-substituted pyrrole derivatives were synthesized through one-pot four-component condensation reaction of aromatic aldehydes, benzylamines, β-ketoesters, and nitroalkanes in the presence of 10 mol % NiCl2·6H2O in good yields. Some of them exhibit properties as potential inhibitors of phosphodiesterase 4B (PDE4B) through docking studies.
Abstract An environmentally friendly, straightforward, and cheap synthesis of highlysubstitutedfunctionalized pyrrole derivatives via one pot four-component reactions of 1,3-dicarbonyl compounds, amines, aromatic aldehydes, and nitroalkanes have been developed. This methodology provides desired pyrroles in good-to-excellent yields in the presence of Fe (III)-Schiff base/SBA-15 as a heterogeneous
