Used in pharmaceutical synthesis as a key chiral building block for developing biologically active compounds. Its rigid bicyclic structure and functional handle make it valuable in the design of enzyme inhibitors and receptor ligands. Commonly employed in the development of central nervous system agents and antiviral drugs due to its ability to mimic natural amino acid geometries. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies, where the scaffold helps optimize potency and metabolic stability.
