Quinolizidines. 6. Absolute Stereochemistry of Ankorine: Synthetic Incorporation of Ethyl Cincholoiponate into (-)-Ankorine

With a view to establishing the absolute configuration of the Alangium alkaloid ankorine, the chiral target molecule 1 was synthesized by means of an initial condensation of 2-(benzyloxy)-3,4-dimethoxyphenacyl bromide with cincholoipon ethyl ester
