Tert-butyl 3,9-diazabicyclo[3.3.1]nonane-9-carboxylate is primarily employed as a key building block in the synthesis of complex heterocycles and pharmacophores. Researchers utilize it in palladium-catalyzed cross-coupling reactions and as a precursor for N-Boc-protected amines in peptide mimetics. Its bicyclic structure is leveraged in designing CNS-targeting compounds due to enhanced blood-brain barrier permeability. The compound also finds utility in asymmetric catalysis and as a ligand in transition-metal complexes.
