Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its structure supports the construction of complex, stereochemically defined targets, making it valuable in medicinal chemistry for creating drug candidates with high selectivity and potency. Commonly employed in solid-phase and solution-phase peptide synthesis due to the presence of protected functional groups that allow selective deprotection and coupling. Also utilized in the preparation of enzyme inhibitors where the azabicyclic scaffold mimics transition states in catalytic mechanisms.
