Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals. Its alkyne group enables click chemistry reactions, such as Cu(I)-catalyzed azide-alkyne cycloaddition (CuAAC), making it valuable for constructing complex molecules in drug discovery. The tert-butyl carbamate (Boc) protected azetidine ring provides a stable scaffold that can be deprotected and further functionalized, allowing for the introduction of nitrogen-containing heterocycles in bioactive compounds. Commonly employed in the synthesis of kinase inhibitors and other medicinal agents where azetidine moieties improve metabolic stability and solubility.
