Ceric Ammonium Nitrate (CAN)–Catalyzed Multicomponent Reactions: An Efficient Catalyst for Green Organic Synthesis

Abstract

Multicomponent reactions (MCRs) consist of two or more synthetic steps carried out without isolation of any intermediate, which reduces time and saves money, energy, and raw materials. The development of MCRs in the presence of ceric ammonium nitrate (CAN) is an efficient approach that meets with requirements of sustainable chemistry. The aim of this review is to highlight the interactive effect of the combined use of MCRs and CAN for the development of new ecofavorable methodologies for synthetic organic chemistry. There are many advantages to the use of CAN as a catalyst in organic synthesis, including the very small amount of this catalyst needed to complete reactions in most cases, lower costs, ecofriendly nature, ease of handling, nontoxicity, and high reactivity.
