Abstract

We synthesized various carbazoles from anilines through a three-step process with good overall yields (up to 48%). This process comprises N-acetylation, copper(0)-mediated Ullmann homocoupling, and acid-mediated intramolecular amination. It permits various functional­ groups on the substrate. Scale-up of the developed three-step synthetic route to carbazoles was also demonstrated.
