Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its protected amine group and stereochemistry make it valuable in asymmetric synthesis and peptide mimetic design. Commonly employed in medicinal chemistry for constructing structurally complex drug candidates, especially those targeting neurological and metabolic disorders. Also utilized in the preparation of intermediates for serotonin and dopamine receptor modulators.
