Stereoselective palladium(0)-mediated synthesis of unsaturated 1,4-disaccharides

Unsaturated 1,4-disaccharides are obtained in quite good yields by alkylation of ethyl α-O-Δ2-glycosides, having a leaving group at C-4, with various 1-hydroxycarbohydrates in the presence of a catalytic amount of palladium(0). The reaction is regioand stereospecific for α-erythro enosides 3 and 5, and only stereospecific in the case of the β-threo enoside 7, alkylation occuring at C-4 and C-2 in this case.
