Summary:[Display omitted] •A new method to build the tricyclic bispyrroloquinone framework is described.•The structural assignment of the formed regioisomer is reported.•A proposal of mechanism is given for this new reaction. A one-pot procedure to difunctionalized fused tricyclic bispyrroloquinone derivatives involving the condensation of N-tosylindoledione and α-ketoamines is described.
