Chemoselective microwave-assisted transesterification of 6,1-lactone derived from glucuronic acid is catalyzed by reusable Dawson-type polyoxometalates. These catalysts allow the formation of pseudo-disaccharides from easily available precursors. This permits the expeditious assembly of promising building blocks from precursors obtained from biomass, with easy recycling of the catalyst.
