Used as a chiral building block in organic synthesis, particularly in the development of pharmaceuticals. Its spirocyclic structure and diol functionality make it valuable for creating complex molecules with high enantiomeric purity. It is also employed in asymmetric catalysis, where its rigid framework helps control stereochemistry in reactions. Additionally, it serves as a precursor in the synthesis of ligands for metal complexes, which are used in various catalytic processes. Its unique structure is leveraged in materials science for designing advanced polymers and supramolecular assemblies.
