We report here that polysubstituted dihydroisoquinolones and isoquinolones can be constructed by the one-pot reaction of the readily available acyclic alpha,beta-unsaturated carbonyl precursors and dialkyl glutaconates under mild basic conditions (1-45 min for the former vs. 1-6 h for the latter) via the domino process involving [3+3] annulation/intramolecular aza-cyclization.
