An efficient lactamization strategy using ethyl 3-(6-oxocyclohex-1-en-1-yl)propanoate (3) as the starting material for concise total synthesis of (–)-galanthamine (1) is presented. Naturally occurring phytomedicine (–)-galanthamine was obtained with a total yield of 19.2% in concise steps. This approach features a mild and convenient intramolecular oxidative amidation reaction between aromatic aldehyde and N-carbamate promoted by sodium hydride for synthesis of the key benzo[c]azepine ring.

Key words: (–)-galanthamine, intramolecular oxidative amidation, total synthesis, Alzheimer’s disease
