Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents. It features a spirocyclic isobenzofuran-piperidine structure with a tert-butoxycarbonyl (Boc) protecting group on the piperidine nitrogen, enabling selective modifications and controlled reactivity during synthesis. This makes it valuable for creating potent and selective receptor modulators. Commonly employed in medicinal chemistry for constructing complex piperidine-based scaffolds found in bioactive molecules.
