Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and central nervous system agents. Its structure supports the construction of complex nitrogen-containing heterocycles, making it valuable in medicinal chemistry for creating drug candidates with improved selectivity and metabolic stability. Commonly employed in the preparation of protease inhibitors and receptor modulators due to its rigid, stereochemically defined scaffold. Also utilized in asymmetric synthesis and catalysis where chiral pyrrolidine frameworks are required.
