The preparation of a whole series of peptides —starting from a single precursor—can be achieved with readily available tripeptides such as 1 (R = H). They contain aminomalonate building blocks which can be alkylated with alkyl halides and Michael acceptors under basic conditions in good to excellent yields. By cleavage of the benzyloxycarbonyl group, peptide derivatives 1 , R = alkyl, etc. are obtained, which can then be further modified. Such peptide series are of particular interest, for example, for screenings (“peptide libraries”).
