Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules targeting central nervous system disorders. Its structure provides a rigid bicyclic framework that enhances selectivity and stability in drug candidates. Commonly employed in medicinal chemistry for constructing potent receptor modulators, especially in the design of neurokinin antagonists and serotonin receptor ligands. The tert-butyl carboxylate group allows for easy deprotection and further functionalization, making it valuable in multi-step organic syntheses.
