Novel Synthesis of 5-Substituted 5H-Benzo[b]carbazole-6,11-diones via Double Buchwald–Hartwig Reaction

Abstract

2-Bromo-3-(2-bromophenyl)naphthalene-1,4-dione was synthesized as a key precursor to obtain a number of functionalized benzo[<i>b</i>]carbazole-6,11-diones by double Buchwald–Hartwig coupling reaction.
