Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of enzyme inhibitors and neuroactive agents. Its rigid bicyclic structure and defined stereochemistry make it valuable for designing compounds with high selectivity and potency. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in central nervous system (CNS) drug discovery. Also utilized in asymmetric synthesis to introduce stereochemical control in complex molecule construction.
