Abstract:Huperzine A has been shown to be a second-generation of powerful selective inhibitor of acetylcholinesterase,which is a privileged drug to treat Alzheimer's disease. Because of its unique pharmacological profile and low toxicity,huperzine A has been attracted widespread attention. Synthesis of methyl 6-hydroxy-2-methoxy-7,8-dihydroquinoline-5-carboxylate as a key intermediate for the synthesis of huperzine A was reviewed based on different starting materials and synthetic methods.
Key words:inhibitor of acetylcholinesterase;huperzine a;methyl 6-hydroxy-2-methoxy-7,8-dihydroquinoline-5-carboxylate;synthesis
