Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates that target central nervous system disorders. Its structure enables selective modifications for creating potent receptor ligands, especially in the design of compounds with cognitive-enhancing or neuroprotective properties. Commonly employed in medicinal chemistry for building complex amines due to the protected amine functionality, allowing stepwise elaboration of molecular architecture. Also utilized in the preparation of enzyme inhibitors and receptor modulators where precise stereochemistry and nitrogen positioning are critical for activity.
