Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules requiring constrained nitrogen-containing scaffolds. Its biazetidine core provides structural rigidity, enhancing selectivity and metabolic stability in drug candidates. The tert-butyl carbamate (Boc) protection allows for controlled deprotection in multi-step syntheses, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in the preparation of kinase inhibitors and central nervous system agents.
