Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its rigid bicyclic structure helps stabilize specific molecular conformations, enhancing selectivity and potency in drug candidates. Commonly employed in medicinal chemistry for building blocks in peptidomimetics and CNS-targeted drugs due to its favorable stereochemistry and functional group compatibility. Also utilized in solid-phase and solution-phase peptide synthesis where controlled protection and deprotection are required.
