"New kilogram-synthesis of the Anti-Alzheimer drug (-)-galanthamine";
Tetrahedron Letters, 39 (15) (1998), 2087 - 2088.

English abstract:
A concise, scalable synthesis of (-)-galanthamine, a drug being used for the treatment of Alzheimer's disease, is described. The yield of the crit. phenolic coupling step of I was optimized to 45-50%. For the redn. of the aryl bromide, air-activated LiAlH4 was used and racemic narwedine was converted to (-)-narwedine by a second order asym. transformation.
