A general method for the synthesis of 1,2,3,4-tetrasubstituted pyrroles by [NMPH]CH3SO3 is reported. A full factorial design was performed in order to obtain a more robust and statistically correct optimum condition. The products were obtained in moderate to excellent yields. The developed methodology is very simple, cost-effective, and applicable for tri- and tetra-component reactions. (C) 2019 Elsevier Ltd. All rights reserved.
