Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its rigid bicyclic structure supports the development of conformationally constrained analogs, enhancing selectivity and potency in drug candidates. Commonly employed in the preparation of protease inhibitors and receptor modulators due to its ability to mimic peptide motifs while offering improved metabolic stability. The Boc-protected amine allows for selective deprotection and further functionalization in multi-step syntheses, making it valuable in medicinal chemistry and drug discovery.
