Used as an intermediate in the synthesis of antiviral drugs, particularly in the development of protease inhibitors. Its complex structure allows for high selectivity in biological targeting, making it valuable in pharmaceutical research for hepatitis C and other viral infections. The compound's stereochemistry and functional groups support strong binding to enzyme active sites, enhancing drug efficacy. It is also employed in structure-activity relationship (SAR) studies to optimize potency and metabolic stability in drug candidates.
