Lewis acid promoted imino Diels–Alder reactions of 5-dienyl pyrimidinones with N-aryl/naphthyl imines: synthesis of novel quinoline/benzoquinoline derivatives

The chemo- as well as regioselective imino Diels–Alder reactions of 5-dienyl pyrimidinones with N-aryl as well as N-naphthyl imines in the presence of a different Lewis acid catalysts resulting in novel quinoline and benzoquinoline derivatives are reported.
