REDUCING THE CARBONYL FUNCTIONS OF CARBOHYDRATES AND CARBOHYDRATE DERIVATIVES IN AN AQUEOUS MEDIUM BY MEANS OF SODIUM DITHIONITE
Résumé
The present invention relates to the use of sodium dithionite to reduce at least one aldehyde or ketone function of a carbohydrate, C-glycoside, oligosaccharide, or water-soluble polysaccharide in the absence of a water-immiscible organic solvent and in the absence of a phase transfer agent. The invention also relates to a preparation method that includes treating a carbohydrate, a C-glycoside, an oligosaccharide, or a water-soluble polysaccharide with sodium dithionite.
