RuCl3·3H2O as catalyst for Ferrier rearrangement: An efficient procedure for the preparation of pseudoglycosides

Article abstract of DOI:10.1016/j.tet.2013.09.061

By using RuCl₃·3H₂O as catalyst, an improved method for the synthesis of 2,3-unsaturated-glycosides has been established. A series of 2, 3-unsaturated-glucosides were obtained from 2,4,6-tri-O-acetyl-d- glucal or 3,4-di-O-acetyl-6-deoxy-l-glucal in good yield and high anomeric selectivity.
