Synthesis of multi ring-fused 2-pyridones via an acyl-ketene imine cyclocondensation.

Org. Lett. 8(5) , 935-8, (2006)

Polycyclic ring-fused 2-pyridones (5a-e and 9a-e) have been prepared via a microwave-assisted acyl-ketene imine cyclocondensation. Starting from 3,4-dihydroisoquinolines (4a-b) or 3,4-dihydroharman (8...
