Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of neuroactive compounds, nootropic agents, antivirals, and specific enzyme inhibitors. Its rigid bicyclic 7-azabicyclo[2.2.1]heptane structure, with the tert-butyl carboxylate protecting group at the nitrogen, enables precise control of reactions at other sites during synthesis, enhancing metabolic stability and blood-brain barrier penetration in peptide-like modifications. The protecting group can be easily removed in later steps, making it ideal for structure-activity relationship (SAR) studies targeting central nervous system disorders and for preparing conformationally constrained enzyme inhibitors with improved binding affinity and selectivity.
