Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and other biologically active molecules. Its protected amine and carboxylic acid functionalities allow for selective peptide coupling, making it valuable in solid-phase and solution-phase peptide synthesis. The piperidine ring with defined stereochemistry supports conformational control, enhancing binding selectivity in drug candidates. Commonly employed in the preparation of enzyme inhibitors targeting neurological disorders and viral infections.
