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 structure supports the creation of complex molecules in medicinal chemistry, especially in the design of central nervous system agents and enzyme inhibitors. Commonly employed in asymmetric synthesis due to the stability and stereochemical control offered by the tert-butyl carbamate-protected pyrrolidine scaffold. Widely utilized in research and process chemistry for constructing optically active intermediates.
