Harnessing the chemistry of 4aH-carbazoles: a consecutive rearrangements approach to carbazoles

Abstract

We report a mild method for the synthesis of 4aH-carbazole intermediates with significant synthetic flexibility and variability, and demonstrate the controllable rearrangements of such intermediates to carbazoles. The work further enriches the chemistry of 4aH-carbazoles in general and offers a consecutive rearrangements approach for the precise decoration of the “inert” carbazole ring specifically.
