Used as an intermediate in the synthesis of biologically active compounds, particularly in the development of pharmaceuticals. Its structure allows for selective functionalization, making it valuable in creating peptidomimetics and enzyme inhibitors. Commonly employed in medicinal chemistry for constructing constrained amino acid derivatives that enhance metabolic stability and receptor selectivity in drug candidates. Also utilized in solid-phase synthesis due to the presence of the Boc-protected amine, enabling controlled stepwise assembly of complex molecules.
