Travelling without moving: A Ferrier rearrangement/aza-Wacker cyclization on commercial glycals allows both a 3,4-cis amination at position three and a motion of the double bound restoring the glycal. Epoxidation/glycosylation of N-Ts 3-amino-3-deoxygalactal provided disaccharide with high diastereoselectivity and yield, thus defining FAWEG (Ferrier/Aza-Wacker/Epoxidation/Glycosylation) as a new sequence
