Heterocyclic moieties are basic skeletons for 80% of commercial medicines according to the
US retail market in 2014–2015, yet many actual synthetic methods are not sustainable …

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 …

Multi-component reactions for the construction of heterocycles have been fascinated by
microwave energy as an alternative technique of heating, owing to the advantages over …

2-Aminopyridine is a simple, low molecular weight and perfectly functionalised moiety
known for the synthesis of diverse biological molecules. Many pharmaceutical companies …

Herein, we describe an efficient, rapid and benign protocol for the direct C (sp2)–H bond
halogenation (Cl, Br, I) of 2-arylimidazo [1, 2-a] pyridines using trihaloisocyanuric acids in …

Heterocyclic compounds with two to three nitrogen atoms play a pivotal role in the normal
life cycle of a cell. Further the design and synthesis of a quality heterocyclic compound …

The use of alternative energy sources, such as microwaves (MW) or ultrasounds (US), and
their mutual cross-combination have been widely described in the literature in the …

In this work, a series of phenacyl bromide derivatives was synthesized and employed as key
intermediate for the synthesis of substituted imidazo [1, 2‐a] pyridines. First, phenacyl …

A novel approach for the visible-light-initiated synthesis of 2-amino-4 H-pyran-3, 5-
dicarbonitrile derivatives via a one-pot, three-component reaction of aldehydes or isatins …

Pyrimidine-fused derivatives that are the inextricable part of DNA and RNA play a key role in
the normal life cycle of cells. Pyrimidine-fused dinitrogenous penta-heterocycles, including …
