Abstract

A new π-conjugated system of nitrogen-containing polycyclic compounds was constructed by cationic AuI-catalyzed cycloisomerization. Intramolecular reaction of 9-(2-alkynylphenyl)-9H-carbazole derivatives gave a variety of penta- and hexacyclic compounds possessing a dibenzazepine skeleton. The rigid carbazole structure was responsible for efficient 7-endo-dig cycloisomerization.
