Used in pharmaceutical research as a chiral intermediate for synthesizing biologically active compounds, particularly in the development of protease inhibitors and other enzyme-targeted drugs. Its pyrrolidine-dione structure supports molecular diversity in medicinal chemistry, enabling the exploration of new drug candidates. Commonly employed in asymmetric synthesis due to its stereochemical purity, facilitating the production of enantiomerically enriched molecules. Also utilized in the preparation of peptide mimetics and heterocyclic scaffolds for drug discovery.
