Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds targeting central nervous system disorders. Its rigid, fused bicyclic structure with protected amine functionality makes it valuable in medicinal chemistry for constructing peptidomimetics and kinase inhibitors. The tert-butyl ester group allows for selective deprotection, enabling stepwise assembly of complex molecules. Commonly employed in research settings for drug discovery programs focused on neurodegenerative diseases and psychiatric conditions.
