Abstract: 5H-Chromeno[2,3-b]pyridine derivatives are a series of the most important compounds of
chromenes with industrial, biological, and medicinal properties. These compounds are known as the
privileged medicinal scaffold and can be synthesized by different methods such as multicomponent reactions
(MCRs), Multicomponent coupling reactions (MCCRs), pot, atom, and step economy (PASE).
In this review article, we have focused on the significant reactions for the syntheses and applications of
5H-chromeno[2,3-b] pyridines, including two-component reactions, three-component reactions, fourcomponent
reactions, and multi-step reactions. This review is expected to serve as a useful conceptual
overview and inspire the next generation to develop the different strategies for the preparation of 5HChromeno[
2,3-b] pyridine derivatives.
