Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and drug candidates. Its rigid bicyclic structure makes it valuable for modifying peptide-like compounds, enhancing metabolic stability and target selectivity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in projects involving nitrogen-containing heterocycles. Also utilized in the preparation of novel ligands for central nervous system targets due to its favorable stereochemistry and ability to influence blood-brain barrier penetration.
