Progress in Synthesis of Propargylamine and Its Derivatives by Nanoparticle Catalysis via A3 coupling: A Decade Update

摘要

Propargylamine and its derivatives are important skeletal structure for synthesis of many nitrogen containing active biological and pharmaceutical compounds. They are classically prepared from aldehyde, amine and alkyne (A3 coupling) which proved to be an exciting method since water is the only byproduct with the desired compound. Three component coupling strategies are very attractive research domain in organic chemistry during the past two decades for the synthesis of highly functionalized organic molecules. Molecular diversity in three component reactions ends up with several methods for drug discovery process towards the synthesis of structurally tailored heterocyclic compounds. These one pot transformation processes do involve simultaneous addition of reactants, reagents and catalyst. The reactions are generally carried out by employing several transition metal catalysts. Nanoparticles have shown their potential as catalysts in several fields of chemical research in modern era. Now, they have taken entry in multicomponent reaction system for playing the role of a catalyst. This review highlights a library of metal nanoparticles which have been used in recent years for synthesis of propargylamine and its derivatives via A3 coupling reactions.
