Fixed chirality : The treatment of cyclooctapyrroles (see picture) with a metal source with optically active carboxylate or amine ligands leads to enantioselective metalation to give stereochemically stable helical mononuclear and dinuclear complexes without a chiral auxiliary. The helicity of the dicopper complex was determined by the simulation of the CD spectrum on the basis of X‐ray crystallographic data.
