Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting the central nervous system. Its rigid bicyclic structure provides stability and specific spatial orientation, making it valuable in designing bioactive molecules with improved metabolic resistance and binding selectivity. Commonly employed in the preparation of antiviral agents, receptor agonists, and enzyme inhibitors. Also utilized in the creation of chiral ligands and catalysts for asymmetric synthesis in medicinal chemistry research.
