Application

This compound serves as a key intermediate in the synthesis of biologically active molecules, particularly in the development of central nervous system (CNS) targeting drugs. The Boc-protected piperidine moiety allows for selective deprotection in multi-step syntheses. Researchers utilize this building block for creating spirocyclic analogs with potential receptor binding activity. The dimethoxyindene scaffold may impart interesting electronic properties to derived compounds.
