An efficient and eco-friendly protocol for the synthesis of diverse 4,5-substituted 1H-pyrrole-3-carbonitriles has been developed using commercially available HZSM-5 and Pd/C as recyclable heterogeneous catalysts with more excellent yields (up to 98 %) than traditional liquids acids, and successfully applied in the practical synthesis of vonoprazan. The conspicuous features of this protocol are higher product yield, easy work-up, eco-friendly and reusability of catalysts.
4-Substituted 2-phenyl- and 2-phenyl-3-aryl pyrroles by reaction of tosyl benzyl isocyanide (TosBIC) with Michael acceptors

Synthesis of 2-phenyl and 2,3-diphenylpyrroles bearing at the 4 position electronwithdrawing groups by reaction of tosylbenzylisocyanide (TosBIC) with various Michael acceptors was investigated. Sodium hydride and n-butyllithium were used as deprotonating agents for the synthesis of monophenyl and diphenylpyrroles, respectively.
