Used as a chiral auxiliary or intermediate in asymmetric synthesis, particularly in the preparation of enantiomerically pure sulfonamides and amino derivatives. Its rigid cyclic structure and stereochemical stability make it valuable in controlling stereochemistry during carbon–carbon bond formation or functional group transformations. Commonly employed in medicinal chemistry for the synthesis of bioactive molecules where stereoselectivity is critical. The tert-butyl carbamate-like structure allows for easy deprotection, enabling further functionalization in multistep synthetic routes.
