In multicomponent reactions, three or more reactants combine in one pot to form a product without the isolation of intermediate and most of the reactants contribute to newly formed product reducing number of steps involved and waste generated. Molecular iodine is mild, efficient, relatively nontoxic, inexpensive, commercially available, and catalyzes various organic reactions due to its Lewis acidic behaviour. The development of multicomponent reactions catalyzed by molecular iodine indeed is a good green alternative for synthetic organic chemistry. The aim of this article is to review all important multicomponent reactions catalyzed by molecular iodine reported since 2013 in order to envisage some new efficient protocols for the synthesis of structurally complex molecules.

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.
