Recent advances in the synthesis of pyrroles via multicomponent reactions using arylglyoxals

Pyrrole is widely known as an active pharmacophore. This core framework plays an important role in several natural and biological products. Due to its properties, developing such scaffolds has attracted much attention. The accessibility of these role-playing heterocyclic motifs via easy, high efficiency and developed methodologies is of interest and value in the creation of new heterocyclic compounds. This review highlights the broad range of applications of arylglyoxals in the synthesis of pyrrole derivatives via multicomponent reactions over the period 2010-2019.
