Used as a chiral auxiliary or intermediate in asymmetric synthesis, particularly in the preparation of enantiomerically pure sulfoxides and sulfones. Its rigid cyclic sulfamide structure helps control stereochemistry during carbon-carbon bond-forming reactions. Commonly employed in medicinal chemistry for the synthesis of bioactive molecules where stereoselectivity is critical. The tert-butyl carbamate-protected nitrogen allows for further functionalization, making it valuable in multi-step organic syntheses, especially in the development of pharmaceuticals targeting central nervous system disorders and protease inhibitors.
