Used as an intermediate in the synthesis of antiviral drugs, particularly in the development of hepatitis C virus (HCV) inhibitors. The compound's chiral cyclopentyl backbone and protected amine group make it valuable for constructing nucleoside analogs. It enables selective functionalization in multi-step organic syntheses, especially in pharmaceuticals where stereochemistry is critical. Its hydroxyl and carbamate groups allow for further derivatization, facilitating the creation of biologically active molecules with improved metabolic stability.
