Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of peptidomimetics and bioactive molecules. Its structure supports the construction of constrained amino acid analogs, which are valuable in enhancing metabolic stability and receptor selectivity in drug design. Commonly employed in solid-phase and solution-phase peptide synthesis due to the presence of orthogonal protecting groups. Facilitates the introduction of cyclobutane motifs to influence conformational rigidity, improving pharmacokinetic properties in medicinal chemistry campaigns.
