Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical development. Its structure allows for selective functionalization, making it valuable in constructing constrained peptide analogs and nitrogen-containing heterocycles. Commonly employed in medicinal chemistry for the preparation of cyclobutane-based scaffolds, which can enhance metabolic stability and binding affinity in drug candidates. Also utilized in the development of protease inhibitors and kinase modulators due to its ability to mimic peptide bonds while introducing conformational rigidity.
