Used primarily as a building block in organic synthesis, especially in the development of pharmaceuticals. Its strained ring system makes it valuable for constructing complex molecular architectures with specific stereochemistry. Commonly employed in the synthesis of bioactive compounds, including central nervous system agents and enzyme inhibitors. The amine functionality allows for easy derivatization, enabling its use in medicinal chemistry for structure-activity relationship studies. Also utilized in the preparation of novel ligands for catalysis and in the design of conformationally restricted analogs of biologically active molecules.
