is one of the top ten leading causes of death over the world, and lipoarabinomannan (LAM) has been confirmed to play significant roles in this process. In this study, a convenient synthetic approach has been developed for the synthesis of oligosaccharides derived from LAM starting with commercially available substrates and reagents. The key steps for stereoselective construction of glycosidic bonds by
