Used as a chiral auxiliary in asymmetric synthesis, enabling the formation of stereoselective carbon-carbon bonds. It is particularly valuable in the pharmaceutical industry for the synthesis of optically active intermediates. The compound helps control stereochemistry during reactions such as alkylations, aldol condensations, and Michael additions. After serving its role, it can be cleaved under mild conditions, leaving the desired enantiomerically enriched product. Its stability and ease of introduction make it a preferred choice in complex molecule assembly, including natural products and active pharmaceutical ingredients.
