Abstract The synthesis of α- d -galactofuranosyl-(1→2)- d -galactitol, which has been isolated by reductive β-elimination from glycoproteins of Bacteroides cellulosolvens and Clostridium thermocellum , is described. The approach of selective glycosylation of an aldono-1,4-lactone by the trichloroacetimidatemethod was employed. The synthesis of α- d -Gal f -(1→2)[β- d -Gal f -(1→3)]- d -Galol, that
