Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of protease inhibitors and central nervous system (CNS) active compounds. Its constrained seven-membered ring structure with a defined stereochemistry enhances binding selectivity and metabolic stability in drug candidates. Commonly employed in the preparation of antiviral and antidiabetic medications where stereochemical precision is critical for biological activity. Also utilized in medicinal chemistry research for scaffold optimization in kinase inhibitors and GPCR-targeted therapeutics.
