  Synthesis of O-1–O-6 Substituted Positional Isomers of d-Glucose–Thioether Ligands and Their Ruthenium Polypyridyl Conjugates

  摘要：

  A library of positional isomers of n-glucose (O-1-O-6) as ligands and their 11 light-active ruthenium conjugates has been synthesized. A protecting group strategy without the necessity of using palladium on carbon for the modification for the 2-O and 4-O position allows for the incorporation of sulfur donor atoms as ligands for transition metal complexes.

  An efficient chemical synthesis is described for the title trisaccharide repeating unit of the capsular polysaccharide of Streptococcus pneumoniae Type 19F. The key intermediate was a well-accessible indirect β-D-mannosaminyl donor, i.e. 2-(benzoyloxyimino)-2-deoxy-α-D-arabino-hexopyranosyl bromide, which underwent glycosidations with 20 : 1 β-selectivities; the benzoyloxyimino group was reduced with

  Salidroside is a phenylpropanoid glycoside isolated from Rhodiola rosea L., a traditional Chinese medicinal plant, and has displayed a broad spectrum of pharmacological properties. In this paper, about 18 novel salidroside analogues were prepared through Koenigs–Knorr method, the effects of these compounds over PC12 was assessed with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) method. The novel compounds differ in the substituents attached to the benzene ring or in the glycosyl donor. According to the data, compounds (3,5-dimethoxyphenyl)methyl β-D-glucopyranoside and (3,5-dimethoxyphenyl)methyl β-D-galactopyranoside with methoxy group at 3 and 5-positions of the benzene ring were the most viability at concentration of 300 μmol/l and 60 μmol/l, respectively.

  Bi(NO3)(3), a low-cost, mild, and environmentally green catalyst, has been successfully utilized for Fischer glycosylation for the synthesis of alkyl/aryl glycopyranosides by reacting unprotected sugars, namely, D-glucose, L-rhamnose, D-galactose, D-arabinose, and N-acetyl-D-glucosamine with various alcohols in good to excellent yields. The glycosides were formed with high alpha-selectivity. Further, an expedient separation of alpha- and beta-glycosides using silver nitrate-impregnated silica gel flash liquid chromatography has been developed.
