Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other biologically active compounds. Its rigid azabicyclic structure makes it valuable in medicinal chemistry for conformational restriction, helping to enhance potency and selectivity of drug candidates. Commonly employed in asymmetric synthesis due to its chiral centers, enabling the preparation of enantiomerically pure substances. Also utilized in the preparation of enzyme inhibitors where the tert-butyl carbamate (Boc) protected nitrogen allows for controlled deprotection and further functionalization in multi-step reactions.
