In this work we studied a series of polar Diels-Alder reactions using different heterocycles derivatives acting as electrophiles joint to dienes of different nucleophilicity, analyzing the effect of the microwave irradiation in these processes. We employ the technique in two conditions: benzene as solvent and solvent free reactions. The last one presents the better yield in shorter time of reaction. Using microwave heating the aromatic cycloadducts are clearly predominant. It is possible to demonstrate that the microwave irradiation has a better influence on these cycloaddition reactions respect to those developed in thermal classical conditions.
