Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex cyclic frameworks. The Boc-protected amine group enables controlled deprotection and coupling reactions, ideal for peptide-like synthesis and drug discovery research. Commonly employed in the preparation of analogs for biological evaluation due to its rigid, polycyclic backbone that can mimic natural substrates.
