Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules and drug candidates. Its rigid bicyclic structure and functional groups make it valuable for constructing complex heterocyclic systems, often found in protease inhibitors and central nervous system agents. The Boc-protected amine allows for selective deprotection and further derivatization in multi-step organic syntheses, especially in peptide-like frameworks. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its stereochemical stability and ability to mimic proline-like scaffolds.
