Glycosylation with trichloroacetimidates in ionic liquids: Influence of the reaction medium on the stereochemical outcome

[GRAPHICS] The glycosylation with trichloroacetimidates derived from different glycopyranoses bearing a nonparticipating group at C-2 was explored in different ionic liquids as solvents. The stereoselectivity of the reaction was significantly affected by the reaction media and by the anomeric configuration of the donor.
