Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its hydroxyl and protected amine functional groups allow for selective modifications, making it valuable in constructing complex molecules such as neuroactive drugs and antiviral agents. Commonly employed in medicinal chemistry for the preparation of pyrrolidine-based drug candidates, including those targeting central nervous system disorders. Also utilized in asymmetric synthesis and as an intermediate in the production of protease inhibitors.
