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

Working Paper
This content is a preprint and has not undergone peer review at the time of posting.

Abstract

We report here a novel strategy for the synthesis of 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.
