Used as an intermediate in pharmaceutical synthesis, particularly in the development of biologically active compounds. The presence of both the cyano group and the protected azetidine ring makes it valuable for constructing complex molecules, especially in medicinal chemistry targeting enzyme inhibitors or receptor modulators. The Boc-protecting group allows for selective deprotection under mild acidic conditions, enabling stepwise synthesis in multi-step reactions. Commonly employed in the preparation of drug candidates where the azetidine scaffold contributes to metabolic stability and improved pharmacokinetic properties.
