Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of beta-lactam antibiotics. It serves as a building block for constructing complex organic molecules due to its reactive keto and ester functional groups. Commonly employed in research settings for preparing enzyme inhibitors and bioactive molecules. Also utilized in asymmetric synthesis to introduce chiral centers in drug candidates. Its structure allows for selective modifications, making it valuable in medicinal chemistry for optimizing pharmacokinetic properties.
