Cover Feature: A Concise Synthesis of Oligosaccharides Derived From Lipoarabinomannan (LAM) with Glycosyl Donors Having a Nonparticipating Group at C2 (Eur. J. Org. Chem. 14/2020)

The Cover Feature shows kids (chemists) building blocks with monosaccharides “building blocks” through a convenient method. The key steps for stereoselective construction of glycosidic bonds by acceptors glycosylated with donors without neighboring participating group were achieved. After several steps and one step birch reaction, 5 oligosaccharides with terminal amino group at the anomeric substituent were obtained which will be used for conjugation with TB protein as potential vaccine candidates against tuberculosis.
