Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system (CNS) agents and neuroactive drugs. Its Boc-protected tetrahydropyridine structure allows selective functionalization, making it valuable in constructing complex nitrogen-containing heterocycles. Commonly employed in medicinal chemistry for building blocks in dopamine receptor modulators and other bioactive molecules. Also utilized in solid-phase and combinatorial synthesis due to its stability and reactivity profile.
