Multicomponent reactions (MCRs) refer to reactions in which three or more reactants combine to form a single product in a single step. These reactions are highly efficient and enable the rapid synthesis of complex molecules with diverse structures. MCRs have gained significant interest in the field of organic synthesis due to their ability to streamline the synthesis process, reduce the number of reaction steps, and increase the overall yield of the desired product. They are particularly useful in the drug discovery and materials science fields, where the synthesis of complex molecules is essential. Overall, multicomponent reactions have proven to be valuable tools for the efficient and sustainable synthesis of various organic compounds.
