Deoxy-2-dimethoxyphosphoryl-D-glucopyranose (this usage of phosphoryl is given in [13], Section D, Rule 5.68, and [14], p. 65) or dimethyl 2-deoxy-D-glucopyranos-2-ylphosphonate...

Similarly, the mannopyranosyl analog (346) was synthesized by condensation of di-O-isopropylidene-a-DL-carba-mannopyranose (349) with 348. The other isomer (347) was obtained by reaction of 278 with tetra-O-benzoyl-a-D-mannopyranosyl bromide (350). The four carba-glucopyrano-syl D-mannopyranosides, including 346 and 347, show no antiviral activity. 

Benzyl 2-acetamido-6-0-benzyl-2,4-dideoxy-4-fluoro-a-D-glucopyrano-side and the corresponding free sugar were prepared from benzyl 2-acet-amido-3-0-allyl-6-0-benzyl- (or -3,6-di-0-benzyl)-2-deoxy-a-D-galacto-pyranoside by treatment with DAST (in diglyme). 

To study the binding mode of the yS-D-galactopyranosyl residue of the Lewis b human blood-group determinant to its monoclonal antibody or to a lectin, methyl 2-acetamido-2-deoxy-3-0-(6-deoxy-6-fluoro-2-0-a-L-fuco-pyranosyl-y -D-galactopyranosyl)-4-0-a-L-fucopyranosyl-/ -D-glucopyrano-side was synthesized. ...

The augmented formula of p. 30 for melezitose, S-[a-T)-glucopyrano-ayr -a-fructofuranose < > d-glucopyranose, lacks only the two pertinent a,j9 allocations. In the case of the D-glucopyranose unit there is evidence from enzyme studies, which seems conclusive, that it is of the a-D-type, as in sucrose. First, there is the evidence of a negative kind that the... 

Besides di- and poly-saccharides, zeolites have been applied for hydrolysis of simple glycosides as described by Le Strat and Morreau.132 Methyl a- and /i-D-glucopyrano-sides were treated with water in the presence of dealuminated HY faujasite with an Si/Al ratio of 15, at temperatures ranging between 100 and 150 °C. It was observed that the reaction rate for the (i glycoside was about 5-6 times higher than that for the oc anomer, a result that might arise from the shape-selective properties of the zeolite and stereoelectronic effects on the surface of the solid.

The regioselective esterification at position 6 of a-D-glucose and a-D-glucopyrano-sides with fatty acids [81] is readily achieved by use of Novozym 435, in accordance with Scheme 8.56. 

On oxidation of the phenylosotriazole derivative of the disaccharide with sodium periodate, three moles of periodate are consumed with the formation of one mole each of formic acid and formaldehyde per mole of the phenylosotriazole derivative. If the D-glucose in the u-glucopyrano-syl-L-arabinose phenylosotriazole were attached to carbon atom 4 of the L-arabinose derivative, oxidation of this compound with sodium periodate would require two moles of periodate and would liberate one mole of... 

Proof of Constitution.—Since the crystalline a- and 8-forms of 3,4,6-trimethyl-D-glucose, isolated by Sundberg and coworkers,28 were each obtained by hydrolysis of methyl 3,4,6-trimethyl-/3-D-glucopyrano-side,82,154 the proof of the constitution of this glucoside obviously played an important part in the characterization of the trimethylglucose itself. Unfortunately, there is no such crystalline reference compound to correlate the earliest samples of sirupy 3,4,6-trimethyl-D-glucose157,168 with the crystalline specimens isolated by Sundberg and coworkers. 

In the aldohexopyranose series, treatment of methyl 2,3-anhydro-4,6-di-O-methyl-a-D-allopyranoside (34), or of the corresponding 4,6-diacetate (39), with hydrogen tetrafluoroborate in hydrogen fluoride at 70° afforded121 the corresponding derivatives of 2-deoxy-2-fluoro-D-al-tropyranosyl fluoride (35 and 40) and 3-deoxy-3-fluoro-D-glucopyrano-syl fluoride (36 and 41). Compounds 35 and 36 were hydrolyzed, and...
