Synthesis of a Pentaarylcarbazole: Installation of Different Aryl Groups on a Benzenoid Moiety

We report here a novel strategy for the synthesis of 1,2,3,4,9-pentaarylcarbazole. In this method, an N-alkynylation of sulfonamide facilitated by an iodonium salt, and spontaneous cycloaddition of the resulting ynamide were crucial for the rapid construction of the central carbazole core.
