Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. Its strained cyclobutane ring and functional groups make it valuable for constructing complex organic frameworks. Commonly employed in medicinal chemistry for structure-activity relationship studies, especially in optimizing drug candidates for improved metabolic stability and binding affinity. Also utilized in the preparation of enzyme inhibitors and receptor modulators due to its conformational rigidity and ability to mimic peptide motifs.
