Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its protected amine and hydroxyl functional groups allow for selective chemical modifications, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in solid-phase and solution-phase peptide-like synthesis due to its rigid bicyclic scaffold, which can enhance the metabolic stability and binding affinity of drug candidates.
