Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require chiral, nitrogen-containing heterocyclic structures. Its rigid, bicyclic framework with defined stereochemistry makes it valuable in medicinal chemistry for enhancing selectivity and potency of drug candidates. Commonly employed in the preparation of kinase inhibitors and central nervous system (CNS) agents due to its ability to mimic peptide motifs and cross biological membranes. Also utilized in asymmetric synthesis and catalysis as a chiral building block.
