Used in pharmaceutical research as a key intermediate in the synthesis of complex heterocyclic compounds with potential bioactivity. Shows promise in the development of anti-inflammatory and neuroprotective agents due to its structural similarity to natural indole alkaloids. Also employed in studies exploring spirocyclic scaffolds for drug design, particularly in central nervous system therapies. Its rigid spiro framework enhances metabolic stability, making it valuable in optimizing lead compounds for improved pharmacokinetics.
