Used primarily as an intermediate in the synthesis of pharmaceutical compounds, especially in the development of biologically active molecules. Its structure allows for the introduction of cyclopropane amino acid motifs, which are valuable in drug design for enhancing metabolic stability and improving binding selectivity. Commonly employed in peptide mimetics and protease inhibitor research. Also utilized in solid-phase and solution-phase peptide synthesis where protected functional groups are required. The Boc-protected amine enables controlled deprotection under mild acidic conditions, making it compatible with multi-step synthetic routes.
