Within this thesis, novel rhodium and iridium catalysts were designed and tested in asymmetric catalysis. Herefore, organometallic complexes comprising pendant linkers were conjugated to biologically active peptides. The resulting metalla affinity labels facilitate selective, directed and covalent attachment of the metal centers to the catalytically active protease amino acids. The resulting defined embedment of the organometallic catalysts into the enzyme’s active site results in effective transfer of the protein scaffold’s chiral information, which can be considered to be one of the catalyst’s ligands. With this modular system, enantiomeric excesses of up to 64% were obtained.
