The indole nucleus is a privileged heterocyclic scaffold, which is present in several natural and synthetic compounds. New synthetic strategies to access functionalizedindoles have therefore attracted the attention of both synthetic and medicinal chemists over the decades. In this study, the bismuth nitrate-promoted disproportionative condensation of indoles with cyclohexanone in one pot, to yield
