Used as a chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals where stereochemistry plays a critical role. Its structure allows for selective transformations in asymmetric synthesis, making it valuable in the development of enzyme inhibitors and receptor modulators. Commonly employed in the preparation of β-amino acid derivatives and peptidomimetics, which are important in drug discovery for improving metabolic stability and bioavailability. The presence of both carboxylic acid and protected amine functionalities enables peptide coupling and further functionalization, facilitating its incorporation into complex molecular architectures.
