Used as an intermediate in pharmaceutical synthesis, particularly in the production of active pharmaceutical ingredients (APIs) requiring chiral amine functionalities. Its bicyclic structure and protected amine groups make it valuable in asymmetric synthesis and catalysis. Commonly employed in the development of protease inhibitors and central nervous system agents due to its ability to mimic peptide bonds and enhance metabolic stability. Also utilized in solid-phase synthesis and as a building block in combinatorial chemistry for drug discovery.
