A practical synthesis of a new bifunctionaldiketopiperazine (DKP) scaffold 1, formally derived from the cyclization of l-aspartic acid and (S)-2,3-diaminopropionic acid, is reported. DKP-1 bears a carboxylic acid and an amino functionalities in a cis relationship, which have been used to grow peptide sequences. Tetra-, penta-, and hexapeptidomimetic sequences were prepared by solution-phase peptide
