Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and biologically active compounds. Its rigid bicyclic structure makes it valuable in the design of conformationally restricted molecules, aiding in the development of drugs with improved selectivity and metabolic stability. Commonly employed in medicinal chemistry for structure-activity relationship studies, especially in central nervous system agents and enzyme inhibitors. Also utilized in the synthesis of chiral ligands and catalysts for asymmetric reactions.
