Unexpected furanose/pyranose equilibration of N-glycosyl sulfonamides, sulfamides and sulfamates
Suthagar, Kajitha,Polson, Matthew I. J.,Fairbanks, Antony J.
, p. 6573 - 6579 (2015)
De-protected arabino N-glycosyl sulfamides, sulfonamides and sulfamates were found to mutarotate and convert from the furanose to the thermodynamically more stable pyranose form in aqueous solution. The presence of a strongly electron withdrawing group in
Selective detection of epimeric pentose saccharides at physiological pH using a fluorescent receptor
Gibson, Matthew I.,Neres, Jo?o,Fullam, Elizabeth
, p. 61 - 65 (2014)
Epimerisation between ribofuranose and arabinofuranose sugars is crucial in several biosynthetic pathways, but is typically challenging to monitor. Here, we have screened for fluorescent boronic acids that can be used as molecular probes for the specific detection of ribofuranose over arabinofuranose sugars in solution. We show excellent specificity of the fluorescent response of 3-biphenylboronic acid to ribofuranose at physiological pH. This provides a tool for in situ monitoring of carbohydrate modifying enzymes and provides a viable alternative to traditional radiolabelled assays.

Carbohydrates have played an important role in organic synthesis. Since they contain many stereocenters, they have been widely used as chiral-pool starting materials. Herein, we report the asymmetric formal synthesis of (-)-swainsonine, which exhibits anticancer and immunosuppressive activities and inhibits lysosomal α-mannosidase activity, from D-mannose and D-arabinose. The synthesis utilized Zn-mediated Bernet-Vasella reaction, Horner-Wadsworth-Emmons olefination, and Grubbs olefin metathesis as key reactions.

-
Paragraph 0039; 0041-0042, (2021/09/04)
The invention discloses novel saccharide bio-based cyclic phosphorus/phosphonate as well as a preparation method and application thereof, and belongs to the field of compounds. The cyclic phosphorus/phosphonate is prepared by the following steps: reacting D-xylose with acetyl chloride to obtain an intermediate product, and then reacting with dichlorophosphate or phosphonic dichloride under the action of an acid-binding agent to obtain a target product. The preparation method is high in yield, simple in process, low in raw material cost and small in environmental pollution, and the prepared cyclic phosphorus/phosphonate flame retardant is outstanding in flame retardance and easy to industrialize.
Stereoselective Synthesis of Ribofuranoid exo-Glycals by One-Pot Julia Olefination Using Ribofuranosyl Sulfones

, p. 657 - 673 (2020/12/23)
One-pot Julia olefination using ribofuranosyl sulfones is described. The α-anomers of the ribofuranosyl sulfones were synthesized with complete α-selectivity via the glycosylation of heteroarylthiols using ribofuranosyl iodides as glycosyl donors and the subsequent oxidation of the resulting heteroaryl 1-thioribofuranosides with magnesium monoperphthalate (MMPP). The Julia olefination of the α-ribofuranosyl sulfones with aldehydes proceeded smoothly in one pot to afford the thermodynamically less stable (E)-exo-glycals with modest-to-excellent stereoselectivity (up to E/Z = 94:6) under the optimized conditions. The E selectivity was especially high for aromatic aldehydes. In contrast, the (Z)-exo-glycal was obtained as the main product with low stereoselectivity when the corresponding β-ribofuranosyl sulfone was used (E/Z = 41:59). The remarkable impact of the anomeric configuration of the ribofuranosyl sulfones on the stereoselectivity of the Julia olefination has been rationalized using density functional theory (DFT) calculations. The protected ribose moiety of the resulting exo-glycals induced completely α-selective cyclopropanation on the exocyclic carbon-carbon double bond via the Simmons-Smith-Furukawa reaction. The 2-cyanoethyl group was found to be useful for the protection of the exo-glycals, as it could be removed without affecting the exocyclic C=C bond.
