Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules containing pyrrolidine scaffolds. The cyano and silyloxy functional groups allow for further chemical transformations, enabling the introduction of diverse substituents. The tert-butyl carbamate (Boc) group provides protection for the nitrogen atom, making it valuable in multi-step organic syntheses where selective reactivity is required. Commonly employed in medicinal chemistry for constructing complex nitrogen-containing heterocycles.
