Used as a chiral auxiliary in asymmetric synthesis, enabling the stereocontrolled formation of complex organic molecules. Its rigid structure facilitates high enantioselectivity in alkylations, aldol reactions, and Michael additions. Commonly employed in pharmaceutical intermediates synthesis where precise stereochemistry is critical. After serving its role, it can be cleaved under mild conditions, leaving the desired chiral product intact. Also applied in the development of bioactive compounds and natural product synthesis due to its reliability in inducing the correct stereocenter.
