Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its structure supports the formation of complex amine-based molecules, making it valuable in the production of central nervous system (CNS) agents and metabolic disorder treatments. Commonly employed in asymmetric synthesis due to the stability and reactivity of the pyrrolidine core. Also utilized in the preparation of protease inhibitors and receptor modulators where stereochemistry plays a critical role in biological activity.
