ABSTRACT

A cycloaddition reaction is a pericyclic reaction in which two or more unsaturated compounds combine with the formation of a cyclic adduct. Cycloaddition reactions have been greatly benefited from the use of microwave irradiation not only by completing the reactions in few minutes, but avoiding many of the disadvantages of the conventional reaction conditions like solvent evaporation and poor yield. As MORE (Microwave organic reaction enhancement) chemistry provides cleaner reaction products as well as conditions for carrying out those reactions, which are unattainable under conventional heating conditions. Microwave-assisted cycloaddition reactions give rapid access to fused multicyclic and heterocyclic systems in a single step process.
