The three-component reaction of isoquinolines, dialkyl acetylenedicarboxylates, and 5,6-unsubstituted 1,4-dihydropyridines in acetonitrile at room temperature afforded functionalized isoquinolino[1,2-f][1,6]naphthyridines good yields with high diastereoselectivity. More importantly, the formal [2 + 2] cycloaddition acetylenedicarboxylates refluxing gave unique 2-azabicyclo[4.2.0]octa-3,7-dienes as major products 1,3a,4,6a-tetrahydrocyclopenta[b]pyrroles minor via further rearrangement.
