Two oligosaccharide derivatives, β-D-Glcp-(1-6)-β-D-Glcp-(1-6)- β-D-Glcp-(1-6)-β-D-Glcp-(1-4)-α-D-ManpOMe (1) and β-D-Glcp-(1-6)-β-D-Glcp-(1-6)-β-D-Glcp-(1-6)-β-D-Glcp-(1-6) -β-D-Glcp-(1-6)-β-D-Glcp-(1-4)-α-D-ManpOMe (2), have been synthesized efficiently using a convergent glycosylation strategy of 2 + 3 and 2 + 5.1,6-Anhydro-β-D-glucopyranose, which was prepared from cotton pyrolysis, was applied as a key synthon in the synthesis, significantly simplifying the preparation. The bioassay suggested that these two oligosaccharides can both stimulate the growth of maize cultured in liquid medium at a concentration of 3 ppm.
Synthesis of the C-linked disaccharide α-D-man-(1→4)-D-man employing a SmI2-mediated C-glycosylation step: En route to cyclic C-oligosaccharides
Mikkelsen, Lise Munch,Skrydstrup, Troels
, p. 2123 - 2128 (2007/10/03)
Investigations are reported on the assembly of the C-linked disaccharide α-D-Man-(1→4)-D-Man, representing the first steps in our projected synthesis of a cyclic C-oligomer containing repeating units of this C-dimer. The key step in this synthesis uses a
Regioselective benzoylation of sugars mediated by excessive Bu2SnO: Observation of temperature promoted migration
Zhang, Zhiyuan,Wong, Chi-Huey
, p. 6513 - 6519 (2007/10/03)
Regioselective benzoylation of carbohydrates using an excess of dibutyltin oxide (Bu2SnO) at increased reaction temperatures has been developed for the synthesis of several glycoside benzoates with one or two free hydroxyl groups, including gal
Parasite glycoconjugates. Part 6. Chemical synthesis of phosphorylated penta- and hepta-saccharide fragments of Leishmania major antigenic lipophosphoglycan
Nikolaev, Andrei V.,Watt, Gregory M.,Ferguson, Michael A. J.,Brimacombe, John S.
, p. 969 - 979 (2007/10/03)
The phosphorylated branched oligosaccharides 1 and 2, fragments of the phosphoglycan portion of Leishmania major lipophosphoglycan, have been synthesized using the trichloroacetimidate method for the glycosylation reactions and the phosphoramidite and hydrogenphosphonate methods for phosphorylation.
Synthesis of mono- and dimannoside phosphoramidite derivatives for solid-phase conjugation to oligonucleotides
Akhtar,Akhtar, Saghir,Routledge,Routledge, Anne,Patel,Patel, Ramila,Gardiner,Gardiner, John M.
, p. 7333 - 7336 (2007/10/02)
Mannose and dimannose derivatives have been prepared with an anomerically-linked hydrophobic spacer, and converted to phoshoramidite derivatives suitable for conjugation to oligoribodeoxynucleotides on a DNA/RNA synthesizer. Synthesis of a monomannoside-linked 15-mer oligoribodeoxynucleotide is reported.
Oxidative Cleavage of 4,6-O-Benzylidene Ring with t-Butyl Hydroperoxide and Copper(II) Chloride. Preparation of Methyl 4-O- and 6-O-Benzoylhexopyranoside Derivatives

, p. 1699 - 1702 (2007/10/02)
Copper(II) chloride and palladium(II) acetate were found to be highly effective catalysts for oxidative cleavage of O-benzylidene ring with t-butyl hydroperoxide.Using the former catalyst 4,6-O-benzylidenehexopyranoside derivatives were converted into the

The formation of 4,6-acetoxonium and benzoxonium ion derivatives of methyl gluco-, manno-, galacto- and idopyranosides from the 6-azido-6-deoxy compounds on treatment with nitrosonium ion is described and the formation and rearrangement of the 3,5-benzoxonium ion derived from methyl α-d-xylofuranoside discussed.
REGIOSELECTIVE O-DEACYLATION OF FULLY ACYLATED GLYCOSIDES AND 1,2-O-ISOPORPYLIDENEALDOFURANOSE DERIVATIVES WITH HYDRAZINE HYDRATE
