Used in organic synthesis as an intermediate for pharmaceuticals, particularly in the development of bioactive molecules and heterocyclic compounds. Its rigid bicyclic structure and functional groups make it valuable for constructing complex ring systems in medicinal chemistry. Commonly employed in reactions involving enolate formation or nucleophilic substitution to build nitrogen-containing scaffolds found in drug candidates. Also applied in research settings for designing enzyme inhibitors and central nervous system agents due to its structural similarity to proline derivatives.
