Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its rigid bicyclic structure helps enhance metabolic stability and binding selectivity in drug candidates. Commonly employed in peptide mimetics and solid-phase synthesis due to the presence of orthogonal protecting groups. Facilitates the construction of conformationally constrained scaffolds important in medicinal chemistry for optimizing potency and pharmacokinetic properties.
