Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and bioactive molecules. Its structure allows for easy modification in peptide-like frameworks, making it valuable in medicinal chemistry for developing enzyme inhibitors or receptor ligands. Commonly employed in the synthesis of β-lactam antibiotics and other nitrogen-containing heterocycles. Also utilized in asymmetric synthesis due to its chiral compatibility and ability to act as a building block in multistep reactions.
