yield by biaryl ether formation from peptidyl ruthenium complexes. Direct comparisons between these two approaches are provided. Transition metal π-complexes of either N-protected or carboxyl-protected amino acids can be used as coupling partners in peptide coupling reactions. Preformed peptidyl ruthenium complexes can be used to synthesize cyclic biphenyl ethers in a combinatorial fashion.
