Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require high enantiomeric purity. Its protected amine group allows for selective reactions in multi-step organic syntheses. Commonly employed in the production of central nervous system (CNS) agents and receptor agonists due to the structural similarity to bioactive pyrrolidine derivatives. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug potency and selectivity.
