Abstract
Glucosides of unsaturated alcohols, bearing different protecting groups at glucose units underwent catalytic metathesis affording bolaamphiphiles with good yields. Tungsten aryloxo-complexes (
1 and
2) were found to be superior catalysts for this process.
The first example of metathesis of carbohydrate derivatives: ω-unsaturared glucosides give metathesis products in the presence of aryloxo-chloro-neopentylidene complex of tungsten and a bicomponent catalyst.
