Three-component direct synthesis of substituted pyrroles from easily accessible chemical moieties using hypervalent iodine reagent
摘要:
A novel and simple three-component system has been developed to synthesize substituted pyrroles from corresponding amines and nitrostyrenes using (diacetoxyiodo)benzene at reflux temperature in ethanol. The good to excellent yields were obtained with different types of functional groups. (C) 2013 Elsevier Ltd. All rights reserved.

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

A simple and highly efficient three-component method using easily available amines, nitrostyrene, and diketones in one pot has been developed for synthesis of pyrroles in the presence of catalytic amounts of iodobenzene and Oxone as oxidant. The protocol has been used to afford wide range of pyrroles in moderate to good yields.
