Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors and neuroactive compounds. Its rigid, polycyclic structure supports high selectivity in drug-receptor interactions, making it valuable in medicinal chemistry for optimizing potency and metabolic stability. Commonly employed in solid-phase and solution-phase peptide-like synthesis due to the presence of orthogonal protecting groups. Facilitates the construction of complex nitrogen-containing scaffolds found in central nervous system (CNS) therapeutics.
