This chemical is primarily used in organic synthesis, particularly in the development of complex molecules. It serves as a key intermediate in the preparation of pharmaceuticals, especially those targeting neurological and psychiatric disorders. Its structure, featuring a spirocyclic system, makes it valuable for constructing rigid frameworks in drug molecules, enhancing stability and bioavailability. Additionally, it is employed in peptide chemistry, where it acts as a protecting group for amines during synthesis, ensuring selective reactions. Its tert-butoxycarbonyl (Boc) group is easily removable under mild conditions, making it a versatile tool in multi-step synthetic processes.
