This compound is primarily utilized in organic synthesis and pharmaceutical research as a key chiral intermediate for the preparation of more complex molecules. It is often employed in the synthesis of peptides and amino acid derivatives due to its protective groups, which safeguard reactive functional groups during chemical reactions. The benzyloxycarbonyl (Cbz) group protects the amine, and the benzyl ester protects the carboxylic acid, enabling selective reactions in multi-step synthetic processes. The 4-oxo group provides a reactive site for further elaboration. Additionally, it finds application in the development of protease inhibitors and other bioactive compounds, where precise control over molecular structure is critical. Its (S) configuration also makes it valuable in asymmetric synthesis.
