Three-component aza-Diels-Alder reactions using Yb(OTf)3 catalyst under conventional/ultrasonic techniques.
The Yb(OTf)3 catalyzed formal aza-Diels-Alder (or Povarov) reaction of cyclopentadiene and 1,3-cyclohexadiene with in situ-generated N-arylimines under conventional/ultrasonic techniques is herein described. This kind of three-component Povarov reaction results in quinoline and phenanthridine derivatives, which are important biological compounds.
