Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antibacterial agents. Its strained bicyclic structure makes it valuable in medicinal chemistry for mimicking transition states in enzyme-catalyzed reactions. Commonly employed in the preparation of beta-lactamase inhibitors and other bioactive molecules where ring strain enhances reactivity or binding affinity. Also utilized in research settings for exploring ring-opening reactions and stereochemical control in organic synthesis.
