Used as a key chiral building block in the synthesis of pharmaceuticals, particularly in the development of protease inhibitors and other biologically active molecules. Its rigid azabicyclic structure and defined stereochemistry make it valuable for designing drugs with high selectivity and potency. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing compounds targeting central nervous system disorders and viral infections. The tert-butyl carbamate (Boc) protecting group allows for selective amine manipulation in multi-step syntheses, enabling efficient coupling reactions while maintaining stereochemical integrity.
