was used as an efficient catalyst for the synthesis of a variety of pyrrole derivativesvia a one-pot, three-component condensation of amines, nitroolefins, and 1,3-dicarbonylcompounds. Good to excellent yields of 72–96% were obtained under reflux in ethanol. The catalyst could easily be recovered and recycled up to six times, resulting in good yields without prolonging the reaction time. This method

An efficient and eco-friendly synthesis of functionalized pyrroles using recyclable montmorillonite clay K10 and KSF catalysts has been described. The clay-catalyzed domino four-component coupling (4CC) of amines, aldehydes, 1,3-dicarbonyl compounds and nitroalkanes produced functionalized pyrroles in good yields. The developed methods offers advantages such as operational simplicity, economical, simple

A simple, convenient, and multicomponent coupling strategy for the synthesis of highly functionalized pyrroles catalyzed by iron(III) salts has been developed. This strategy demonstrated four-component coupling reactions of 1,3-dicarbonyl compounds, amines, aromatic aldehydes, and nitroalkanes without an inert atmosphere. This methodology provides an alternative approach for easy access of highly substituted
