Used in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) where the azetidine scaffold is required. The Boc-protected amine allows for controlled deprotection and coupling reactions, making it valuable in constructing complex drug molecules. Commonly employed in medicinal chemistry for optimizing pharmacokinetic properties and enhancing metabolic stability in drug candidates. Also utilized in the synthesis of kinase inhibitors and other bioactive compounds due to the ring strain and conformational rigidity of the azetidine core.
