The site-selective interconversion of serine and cysteine residues of di- and tripeptides into phenylalanine derivatives, bearing a range of functionalities, has been achieved in high yield and selectivity through the common dehydroalanine intermediate. Through the application and development of the rhodium-catalysed 1,4-addition to alpha,beta-dehydroamino acid moieties with organometallic nucleophiles, a variety of peptides have been successfully modified to contain unnatural amino acid residues in predesignated residue positions.
