Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of active ingredients requiring high enantiomeric purity. Commonly employed in the development of central nervous system agents and antiviral drugs due to its ability to influence stereochemistry in final drug molecules. Also utilized in asymmetric synthesis to induce desired stereo-selectivity in complex organic reactions. Its hydroxyl and pyrrolidine functional groups allow for diverse derivatization, making it valuable in medicinal chemistry and drug discovery research.
