A series of 1,1-bis(indol-3-yl) and 1-(indol-2-yl)-1-(indol-3-yl)-ψ-hydroxyalkanes, prepared from the corresponding indole derivatives and suitable hydroxyaldehydes via routine coupling reactions, were treated with DAST (diethylaminosulfur trifluoride) under mild conditions, to generate a small library of cycloalkanoindoles. Irrespective of the substitution pattern, i.e. whether they are symmetrical
