Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules targeting neurological disorders. Its rigid, polycyclic structure with defined stereochemistry makes it valuable for constructing selective ligands that interact with central nervous system receptors. The Boc-protected amine allows for controlled deprotection and coupling in multi-step syntheses, enhancing its utility in medicinal chemistry for creating structurally complex drug candidates.
