Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of peptidomimetics and enzyme inhibitors. Its protected amine and carboxylic acid functionalities make it suitable for solid-phase and solution-phase peptide synthesis. Commonly employed in the preparation of bioactive molecules where stereochemistry plays a critical role in activity. The Boc-protected amine allows for selective deprotection and further coupling reactions, enabling stepwise assembly of complex organic structures in drug discovery.
