Er(OTf)3 in 2-MeTHF provides a new and eco-friendly process for Ferrier glycosylation of sulfonamides and amino acids with various N-nucleophiles. The stereoselective synthesis of 2,3-unsaturated-N-pseudoglycals was carried out with 3,4,6- tri-O-acetyl-D-glucal and different nucleophiles affording good results in a short time.
