The complexity of carbohydrate structures makes their synthesis challenging. Now, an automated glycan synthesizer is reported which is capable of preparing a library of bioactive oligosaccharides, including a fully protected fondaparinux pentasaccharide. Furthermore, the synthesizer can rapidly assemble arabinans up to 1,080-mer size, starting from monosaccharide building blocks.
