This compound is primarily utilized in organic synthesis as a versatile intermediate for the development of complex molecules, particularly in pharmaceutical research. Its spirocyclic structure makes it valuable for constructing biologically active compounds, such as inhibitors or modulators of enzymes and receptors. It is often employed in the synthesis of peptidomimetics, where its rigid framework helps mimic peptide structures while enhancing metabolic stability. Additionally, it serves as a building block in the preparation of drug candidates targeting neurological disorders, inflammation, or infectious diseases. Its tert-butyl ester group provides protection for the carboxylic acid functionality, facilitating selective reactions in multi-step synthetic processes.
