Heterogenous green catalysis: Application of zeolites on multicomponent reactions

Multicomponent reactions are processes in which three or more reactants are introduced concurrently to deliver a single product that contains the essential parts of the starting materials, and those have emerged in the last few years as an important tool for the development of more sustainable processes in modern synthetic organic chemistry. Still, considering the pronounced attention devoted to zeolites as efficient and selective catalysts for organic transformations, in this work we have reviewed the recent applications of zeolites as catalysts in multicomponent reactions; initially, zeolites modified with transition metals were discussed, followed by zeolites with alkaline metals and in the final section, zeolites in the protonic form.
