Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. Its rigid azabicyclic structure enhances selectivity and metabolic stability in drug candidates. Commonly employed in medicinal chemistry for constructing constrained analogs of amino acids and amines, improving pharmacokinetic properties. Also utilized in the preparation of protease inhibitors and receptor modulators due to its favorable stereochemistry and functional group compatibility.
