Abstract

A copper-catalyzed Nazarov cyclization was carried out under conventional heating conditions and microwave conditions. Under strictly temperature-controlled conditions, the use of microwave irradiation improved the chemical yields. Consequently, the kinetic rate of the microwave irradiation was 5.8 times higher than that of the conventional heating conditions. These observations suggested that the microwave specific effects enhanced the efficiency of the Nazarov reaction.
