Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and drug candidates. Its rigid bicyclic structure helps influence stereochemistry and enhance metabolic stability in medicinal chemistry. Commonly employed in the preparation of protease inhibitors and central nervous system agents. Also utilized in the construction of complex heterocycles through selective functionalization of the azabicyclic core. The tert-butyloxycarbonyl (Boc) protecting group allows for controlled amine reactivity during multi-step syntheses.
