Several chiral neolignan skeletons and a benzodioxane were prepared from a tartrate derivative with the
crucial chiral aryl alkyl ether formation being accomplished with cesium phenolate and 18-crown-6.
These compounds have greater than 96% enantiomeric excess, and this work represents the first successful
synthetic preparation of optically active 8-
