摘要：

Chromium and tungsten alkenyl carbene modified carbohydrates have been synthesized by activation of sugar-based propargylic alcohols with pentacarbonyl-THF complexes followed by addition of methanol. This method has also been exploited in disaccharide synthesis. Higher functionalized carbohydrate skeletons are accessible by Diels-Alder and Michael-type addition reactions.
