Single-step synthesis of 3-hydroxycarbazoles by annulation of electron-rich anilines and quinones


A single-step synthesis of 3-hydroxycarbazoles has been achieved via annulation of electron-rich anilines and quinones in PhMe/AcOH (4:1) at room temperature. This chemistry tolerates various substituted benzoquinones and naphthoquinones, however, is sensitive to both the electronic and steric properties of the anilines. The desired 3-hydroxycarbazole derivatives are generally produced in moderate yield.
