Heterogeneous Catalysis in the Synthesis of Nitrogen‐Containing Heterocyclics

The synthesis of nitrogen‐containing heterocyclic compounds using heterogeneous catalysis is a topic of significant interest in organic synthesis and chemical research. Heterogeneous catalysis offers several advantages over homogeneous catalysis, including easier separation and recovery of the catalyst, reduced waste generation, and potentially higher stability and reusability. In this review, the pivotal role of heterogeneous catalysis in synthesizing nitrogen‐containing heterocyclic compounds is explored. Various types of heterocycles and the specific applications of these compounds in drug discovery and material development are discussed in detail. This review discusses various examples of heterogeneous catalysts employed in the synthesis of nitrogen‐containing heterocycles, including metal oxides, supported metals, metal nanoparticles, zeolites, and other porous materials. Emphasis is placed on the mechanistic insights and reaction pathways facilitated by different catalysts. Additionally, recent advancements and innovations in the field are discussed, including novel catalyst designs, green chemistry approaches, and emerging trends in catalytic materials. The aim is to provide a comprehensive overview of the impact and potential of heterogeneous catalysis in this important area of organic synthesis. This review highlights the critical importance of heterogeneous catalysis in the synthesis of nitrogen‐containing heterocycles. It explores various catalysts, detailing their preparation methods, and the diverse characterization strategies employed to confirm their formation. The review underscores the role of these catalysts in facilitating efficient, sustainable, and selective transformations in organic synthesis, particularly those involving nitrogen‐containing heterocycles as final products.
