Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of antibiotics and other bioactive molecules. Its stereochemical purity makes it valuable in asymmetric synthesis, where it helps control the formation of specific enantiomers. Commonly employed in the development of beta-lactam antibiotics and as an intermediate in the preparation of enzyme inhibitors. Also utilized in the fragrance industry due to its ability to contribute to lactone-based aroma compounds.
