Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and drug candidates. Its structure supports the construction of complex organic frameworks, especially in medicinal chemistry for optimizing potency and metabolic stability. Commonly employed in the preparation of protease inhibitors and receptor modulators due to the constrained azetidine ring, which can enhance selectivity and pharmacokinetic properties. The Boc-protected amine allows for controlled deprotection and further functionalization in multi-step syntheses.
