Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require chiral, nitrogen-containing scaffolds. Its rigid bicyclic structure and protected amine functionalities make it valuable in medicinal chemistry for constructing selective enzyme inhibitors and receptor modulators. Commonly employed in the preparation of protease inhibitors and central nervous system (CNS) agents due to its ability to enhance metabolic stability and bioavailability. Also utilized in asymmetric synthesis and catalysis where controlled stereochemistry is essential.
