Used as a chiral auxiliary in asymmetric synthesis, particularly in enantioselective alkylations and aldol reactions. Its structure enables high stereochemical control, making it valuable in the preparation of optically active pharmaceutical intermediates. Commonly employed in the synthesis of complex natural products and bioactive molecules where precise chirality is required. The compound facilitates efficient enolate formation and directs facial selectivity in bond-forming reactions. After serving its purpose, it can be cleaved under mild conditions, leaving the desired chiral product intact.
