Used as a key intermediate in the synthesis of active pharmaceutical ingredients, particularly in the development of central nervous system agents. Its spirocyclic structure and functional groups allow for selective modifications, making it valuable in medicinal chemistry for optimizing drug potency and metabolic stability. Commonly employed in the preparation of nootropic and neuroprotective compounds due to its ability to influence neurotransmitter systems. Also utilized in research settings for building complex heterocyclic scaffolds in drug discovery programs.
