A new series of pyrrolo[3′,4′:3,4]pyrrolo[1,2-a]furoquinolines/ phenanthrolines and pyrrolo[1,2-a]phenanthrolines were efficiently built up from an 8-hydroxyquinoline derivative or phenanthroline via 1,3-dipolar cycloaddition reaction involving non-stabilized azomethine ylides, generated in situ from the parent furo[3,2-h]quinoliniums/phenanthroliums, in presence of a copper(II) chloride-phenanthroline catalytic system. The methodology combines general applicability with high yields.
