Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for central nervous system (CNS) drugs. Its rigid bicyclic structure and functional groups make it valuable for constructing chiral building blocks in asymmetric synthesis. Commonly employed in the preparation of enzyme inhibitors and receptor modulators due to its favorable stereochemistry and stability. Also utilized in medicinal chemistry for optimizing drug candidates, improving metabolic stability, and enhancing bioavailability.
