Paragraph 0060; 0073; 0076, (2018/08/28)
The invention discloses a preparation method of a clostridium bolteae surface capsular polysaccharide structure derivative and belongs to the field of sugar chemistry. The preparation method comprisesthe following steps: taking glucose as a glycosyl donor to obtain a target beta-glycosidic bond; then successfully synthesizing a disaccharide building block through an oxidization-reduction glucoseC-2 site method; then synthesizing a target oligosaccharide structure which takes the disaccharide building block as a repeating unit, such as the gram-positive bacterium surface capsular polysaccharide structure derivative [arrow3]-alpha-D-Manp-(1arrow4)-beta-D-Rhap-(1arrow]5-Linker. A reducing end of decaose is connected with a connecting arm and is used for connecting protein to form a glycoconjugate for carrying out immunology researches. The method provided by the invention has the advantages of simplicity, time saving, labor saving and low cost; the obtained clostridium bolteae surface capsular polysaccharide structure derivative is possibly used for developing and preparing medicine related to autism.

(-)-Dinemasone B was isolated by Krohn and co-workers from a culture of the endophytic fungus Dinemasporium strigosum and has shown promising antimicrobial activity. Described herein is the first total synthesis of (-)-dinemasone B, (+)-4a-epi-dinemasone B, (-)-7-epi-dinemasone B, and (+)-4a,7-di-epi-dinemasone B. Their absolute configurations were also determined. The developed synthesis features a stereoselective reduction of C-glycosidic ketone, lactonization, and E-olefination of aldehyde starting from d-glucose.
