   Sammanfattning : Several optically active organometallic Phe-AAn-Phe peptidomimetics and macrocyclic Phe-(Phe)n peptides have been synthesized by either intra- or intermolecular peptide bond formation of the corresponding bis(amino acid) derivatives. The key bis(amino acid) derivatives were available from an improved multi-step synthetic route, utilising Horner-Wadswort-Emmons olefination of organometallic aldehydes with phosphonylglycine reagents, enantioselective hydrogenation of didehydro amino acids and classical solution and/or solid phase peptide synthesis methodology.
