Used in the synthesis of pharmaceutical intermediates, particularly in the development of antiviral and anticancer agents. Its chiral structure makes it valuable in asymmetric synthesis, where stereochemistry plays a critical role in drug efficacy. Commonly employed in the preparation of β-amino acid derivatives, which are building blocks for peptidomimetic compounds. These compounds help improve metabolic stability and bioavailability in drug design. Also utilized in research settings for exploring enzyme inhibition and receptor binding due to its constrained cyclobutyl ring influencing molecular conformation.
