Used as a key chiral intermediate in the synthesis of active pharmaceutical ingredients, particularly in the production of antiviral and antidiabetic drugs. Its strained bicyclic structure and stereochemical purity make it valuable for constructing complex molecular frameworks. Commonly employed in asymmetric synthesis to introduce specific stereocenters. Also utilized in the development of protease inhibitors due to its ability to mimic peptide transition states. Its ester functionality allows for further chemical modifications, enabling diverse derivatization in medicinal chemistry research.
