Microwave enhanced Diels-Alder reactions of furan, 2,5-dimetylfuran, 1,3-cyclohexadiene and anthracene with dimethyl acetylenedicarboxylate (DMAD) and diethyl acetylenedicarboxylate (DEAD) give [4+2]-cycloadducts in high yields in domestic microwave oven. Aluminum(III) chloride and dichloromethane in combination with microwave irradiation increased the reaction rate.
Key words: microwave, Diels-Alder reaction, aluminum(III) chloride, solvent effect
