Used as a key intermediate in organic synthesis, particularly in the preparation of bioactive molecules and pharmaceuticals. Its spirocyclic structure serves as a protected form of cyclohexanone, allowing selective reactions at other functional sites. Commonly employed in the synthesis of prostaglandins and other complex natural products where controlled ring-opening and ester transformation are required. The compound’s stability and reactivity make it valuable in multi-step synthetic routes, especially in medicinal chemistry for building cyclic frameworks.
