Used in pharmaceutical synthesis as a chiral building block for developing bioactive molecules, particularly in the production of central nervous system agents and enzyme inhibitors. Its protected amine group allows for selective reactions in multi-step organic syntheses. Commonly employed in the preparation of peptidomimetics and receptor ligands due to its structural rigidity and stereochemical purity. Suitable for solid-phase and solution-phase coupling reactions, especially in the development of drug candidates requiring high enantiomeric specificity.
