Used in pharmaceutical research as a key intermediate for synthesizing bioactive molecules, particularly in the development of kinase inhibitors and CNS-targeted drugs. Its rigid bicyclic structure with a protected amine group makes it valuable for constructing selective receptor ligands. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to constrain peptide-like structures. Also utilized in the synthesis of protease inhibitors and as a scaffold in drug discovery programs targeting neurological disorders.
