The aza-Diels-Alder reactions of cyclopentadiene and cyclo-1,3-hexadiene with various substituted N-arylimines in the presence of Yb/Sc triflates as catalyst in MeCN at room temperature gave quinoline and phenanthridine derivatives in moderate to high yields. Some of the cycloaddition reactions were carried out in ionic liquid.
