Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure allows for selective modification, making it valuable in medicinal chemistry for creating analogs with improved metabolic stability and binding affinity. Commonly employed in solid-phase and solution-phase peptide-like synthesis due to the presence of the Boc-protected azetidine ring, which supports controlled deprotection and coupling steps. Also utilized in the preparation of drug candidates targeting central nervous system disorders and inflammatory diseases.
