This compound is primarily utilized in organic synthesis as a building block for the development of more complex molecules. Its spirocyclic structure makes it valuable in medicinal chemistry, where it is often incorporated into drug candidates to enhance their pharmacological properties. The tert-butyl ester group provides protection for the carboxylic acid functionality, allowing for selective reactions to occur at other sites of the molecule. This compound is particularly useful in the synthesis of peptidomimetics and other biologically active compounds, where it can improve stability and bioavailability. Additionally, it serves as a key intermediate in the preparation of heterocyclic compounds, which are important in the design of new therapeutic agents.
