Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its rigid bicyclic structure and functional groups make it valuable for constructing chiral ligands and catalysts in asymmetric synthesis. Commonly employed in medicinal chemistry for modifying peptide-like structures to enhance metabolic stability and bioavailability. Also utilized in the preparation of protease inhibitors and central nervous system agents due to its favorable solubility and stereochemical properties.
