Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules requiring stereochemical control. Its rigid bicyclic structure and protected amine functionalities make it ideal for selective transformations in medicinal chemistry. Commonly employed in the preparation of enzyme inhibitors and receptor ligands, especially in CNS-targeted drugs and antiviral agents. The compound facilitates efficient introduction of the 2,5-diazabicyclo[2.2.2]octane scaffold, enhancing metabolic stability and binding selectivity in final drug candidates.
