Heterocycles constitute the largest diversity of organic molecules of chemical, biomedical, and industrial significance. They
widely exist in numerous natural products, such as vitamins, hormones, antibiotics, alkaloids, herbicides, and dyes. They are also among
the most frequently encountered scaffolds in numerous drugs and pharmaceutically relevant substances. This review highlights some remarkable
achievements made recently in the application of multicomponent reactions (MCRs) to the design of pyrido- and pyrimidofused
heterocycles by multi-component reactions that have appeared in the last ten years. MCRs reactions can dramatically reduce the
generation of chemical wastes, costs of starting materials, and the use of energy as well as manpower. Moreover, the reaction period can
be substantially shortened.
Keywords: Fused heterocycles, metal catalyst, microwave, multicomponent reactions, pyridine, pyrimidine.
