This review article features selected examples on the synthesis of functionalized pyrroles
that were reported between 2014 and 2019. Pyrrole is an important nitrogen-containing …

This review focuses on providing comprehensive highlights of the recent synthetic pathways
of imidazo [1, 2‐a] pyridines, assisted through transition metal‐catalyzed reactions, multi …

We investigated the catalytic efficacy of supported gold nanoparticles (AuNPs) towards the
selective reaction between o-phenylenediamine and aldehydes that yields 2-substituted …

The multicomponent reaction of aldehydes, amines, and alkynes, known as A3 coupling,
yields propargylamines, a valuable organic scaffold, and has received significant interest …

Herein, we describe an efficient method to prepare polysubstituted pyrroles via a copper
hydride (CuH)-catalyzed enyne–nitrile coupling reaction. This protocol accommodates both …

With the use of N-donor ligands in coordination chemistry receiving significant interest and
attention in the last few decades, benzotriazole has emerged as an ideal molecule that …

A base-promoted three-component cascade reaction of α-hydroxy ketones, malonodinitrile,
and alcohols has been developed, providing a direct and efficient route to a range of …

Rhodium-catalyzed [3+ 2] annulation of diazoenals and N-alkyl imines resulted in N-alkyl-
pyrrole-3-carbaldehyde derivatives. The reaction involves thermal 6π-electrocyclization and …

The development of novel approaches for the preparation of small‐sized heterocyclic
products has remained an extremely attractive but challenging proposition. Copper has …

Multisubstituted pyrroles are important fragments that appear in many bioactive small
molecule scaffolds. Efficient synthesis of multisubstituted pyrroles with different substituents …
