Palladium(O)-catalyzed reaction of various carbohydrates derived from glucofuranose, mannofuranose, ribofuranose, glucopyranose, and glucosamine, bearing a free hydroxyl group, with 1,4-bis-(methoxycarbonyloxy)but-2-ene afforded the corresponding bis-glycosides of butene-1,4-diol. Hydrogenation in the presence of palladium on charcoal of these unsaturated compounds led to the formation of the bis-glycosides of butane-1,4-diol. The condensation was successfully extended to the bis-carbonate of 1,2-bis[(1-hydroxy)propen-2-yl]benzene and derivatives of glucofuranose, ribofuranose and glucosamine.
