Used in organic synthesis, particularly in the preparation of complex natural products and pharmaceuticals. Its protected amine and hydroxyl groups make it a valuable chiral building block for stereoselective reactions. Commonly employed in nucleoside analog synthesis, where the silyl protecting group allows for selective functionalization, and the rigid cyclopentane backbone supports proper spatial orientation in coupling reactions. Frequently utilized in antiviral and anticancer drug development due to its structural similarity to sugar moieties in nucleic acids.
