Used in pharmaceutical synthesis as an intermediate for protease inhibitors, particularly in the development of antiviral drugs. Its chiral structure with multiple stereocenters supports high selectivity in biological targeting, making it valuable in creating active pharmaceutical ingredients (APIs) for treatments involving enzyme regulation, such as antiviral therapies for chronic infections or oncology applications. The tert-butyl carbamate group functions as a protecting group during synthesis, enabling efficient control of bond formation and easy removal to activate the core structure. Commonly employed in research settings for optimizing drug potency and metabolic stability.
