Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its rigid bicyclic structure makes it valuable for constructing sterically constrained peptidomimetics, which can enhance metabolic stability and receptor selectivity. Commonly employed in medicinal chemistry for scaffold diversification and optimization of drug candidates targeting neurological disorders and cancer. Also utilized in the preparation of novel heterocyclic compounds via functionalization of the diketo groups.
