Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of antiviral and central nervous system agents. Its rigid bicyclic structure and defined stereochemistry make it valuable for constructing enantioselective drug candidates. Commonly employed in asymmetric synthesis to introduce stereochemical control, it helps optimize the biological activity and metabolic stability of active pharmaceutical ingredients. Widely utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to influence potency and selectivity.
