Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of antiviral drugs. Its structure allows for selective functionalization, making it valuable in constructing complex molecules with high stereochemical control. Commonly employed in medicinal chemistry for modifying drug candidates to improve metabolic stability and bioavailability. Also utilized in the preparation of prodrugs and protective group strategies due to the stability and ease of removal of the tert-butyl carbamate moiety.
