Abstract
The invention relates to cyclodextrin glycosides and processes for their preparation. The cyclodextrin glycosides according to the invention are cyclodextrins substituted by 2-acetamido-2-deoxyaldoses. These cyclodextrin glycosides are prepared by a process which is characterized in that cyclodextrins are reacted with 2-acetamido-2-deoxyaldoses in an anhydrous acid medium and the reaction products are then treated with a mild base. The cyclodextrin glycosides can be used for solubilization of substances which are sparingly soluble or insoluble in water.
