Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals targeting kinase enzymes. Its structure allows for selective modification in drug design, making it valuable in creating potent and specific inhibitors. Commonly employed in medicinal chemistry for nucleoside analogs and antiviral or anticancer agents. The Boc-protected amine group enables controlled deprotection and coupling in multi-step syntheses, enhancing its utility in building complex molecules.
