The mild, moisture-stable and cheap catalyst Yb(OTf) 3 activates glycosyl N-(phenyl)trifluoroacetimidates in the stereoselective synthesis of 1,2-trans and 1,2-cis glycosides. A suitable choice of the reaction solvent led to good yields and stereoselectivity ratios. The protocol was successfully app
