Abstract: The present disclosure discloses a method for preparation of derivatives of gram-positive bacteria surface capsular polysaccharide, and belongs to the field of carbohydrate chemistry. The present disclosure takes glucose as a glycosyl donor to obtain a target ?-glucosidic bond, then successfully synthesizes a disaccharide building block through a method of redox of a glucose C-2 site, and then takes the disaccharide building block as a repeat unit to synthesize a target oligosaccharide structure such as a derivative [?3)-?-D-Manp-(1?4)-?-D-Rhap-(1?]5-Linker of gram-positive bacteria cell wall capsular polysaccharide. A reduction end of decose is linked with a linker to be linked with a protein to make glycoconjugates for immunological studies. The method provided by the present disclosure is simple, time-saving, labor-saving and low-cost, and the resultant derivatives of the gram-positive bacteria surface capsular polysaccharide may be used for development and preparation of medicine related to autism.
