A series of 3,7-diazacyclohepta[]fluorene derivatives were synthesized via a gold(I)-catalyzed 6-- hydroamination/7-- cycloisomerization domino method. The method exhibits a broad substrate scope, and a plausible mechanism has been proposed. The efficacy of this strategy is further validated by the successful derivatization of 3,7-diazacyclohepta[]fluorene.
