Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules requiring stereochemical control. Its rigid, polycyclic structure supports the construction of complex amines and heterocycles, making it valuable in medicinal chemistry for drug discovery. Commonly employed in asymmetric synthesis and as an intermediate in the preparation of protease inhibitors and central nervous system agents. The benzyl and ester groups allow for selective transformations and protection strategies in multi-step organic syntheses.
