for peptide modification, termed “NXO”, is reported. We describe the utility of these building blocks to prepare new pseudo- and oligopeptides and demonstrate the efficient assembly of modified tripeptides using both conventional liquid phase peptide synthesis and solid supported synthesis. Pertaining to the study of NXO in peptide mimicry, the structure of NXO-incorporating tripeptide β-strand mimics

-oxalic acid or ester group, and uses and synthesis methods. These compounds represent amino acid derivatives, wherein the amine group is turned into an acidic group by the oxalic acid group and the carboxylic acid is turned into an amine functionality by the hydrazine group; as well as peptidomimetics comprising the compound and methods for their synthesis.
