Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical development. Its structure contains both a protected amine and an ester functional group, making it valuable for peptide-like chain elongation and the construction of constrained cyclopropane-containing analogs. Commonly employed in medicinal chemistry for designing protease inhibitors and other targeted therapies where ring strain and steric control influence potency and metabolic stability. Also utilized in solid-phase and solution-phase synthesis due to its compatibility with standard deprotection and coupling conditions.
