Used as a key intermediate in the synthesis of protease inhibitors, particularly in the development of antiviral drugs. Its structural features enable selective binding to enzyme active sites, making it valuable in pharmaceutical research for designing inhibitors targeting HIV and hepatitis C virus proteases. The compound’s chiral centers and functional groups allow for precise stereochemical control during drug synthesis, enhancing potency and reducing side effects. It is also employed in structure-activity relationship (SAR) studies to optimize drug candidates for improved metabolic stability and bioavailability.
