Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of peptidomimetic compounds and bioactive molecules. Its structure supports the construction of constrained cyclic amino acid derivatives, which are valuable in enhancing metabolic stability and improving receptor selectivity in drug design. Commonly employed in medicinal chemistry for solid-phase and solution-phase peptide synthesis, especially where stereochemical control is critical. The Boc-protected amine and ester functionalities allow for selective deprotection and coupling reactions, making it suitable for multi-step synthetic routes in the preparation of enzyme inhibitors and therapeutic agents targeting central nervous system disorders and infectious diseases.
