library of various novel biologically active bisindoles with different substitution patterns was synthesized. Electro‐withdrawing groups on the starting material led to the formation of Povarov‐type structures. Furthermore we could successfully demonstrate that consecutive reactions like cross couplings, reductions or even click reactions on bisindoles are feasible.
