Abstract
The trichloroacetimidates of different glycopyranoses were glycosylated in ionic liquids with different acceptors, affording the corresponding glycopyranosides in fair to excellent yields and allowing to recycle the solvent without additional Lewis acid. Key words
carbohydrates - ionic liquids - glycosylations - green chemistry - stereoselectivity
