Ethyl 6-O-acetyl-2,3,4-tribenzyl-1-thio-d-glucopyranoside, as a mixture of anomers, was employed for the stereoselective synthesis of the potassium salt of (2R)-2-O-α-d-glucopyranosyl-(1→6)-α-d-glucopyranosyl-2,3-dihydroxypropanoic acid (α-d-glucosyl-(1→6
Indium(III) triflate: A highly efficient catalyst for reactions of sugars
Giri, Santosh Kumar,Verma, Monika,Kartha, K. P. Ravindranathan
experimental part, p. 464 - 478 (2009/04/06)
Indium(III) trifluoromethanesulfonate has been found to be extremely efficient in catalyzing acyl transfer reactions of various carbohydrates and their derivatives. Selective acetolyses of certain benzyl ethers/isopropylidene acetals of sugars have been possible using In(OTf)3 in Ac2O (neat). Reaction of the per-O-acetate of 2-deoxy-2-phthalimido-D-glucose with benzyl mercaptan in the presence of In(OTf)3 led to the formation of the corresponding thioglycoside in high yield. Facile formation and hydrolysis of the isopropylidene and benzylidene acetals of various carbohydrates have also been achieved very efficiently in the presence of In(OTf)3. The results show great promise for In(OTf)3 in synthetic carbohydrate chemistry.

Fully O-benzylated methyl α-d-glucopyranoside shows a steady order in stepwise debenzylation when it is treated with sulfuric acid in acetic anhydride. Based on the order of debenzylation, regioselective preparations of 2,3,4-tri-, 2,3-, 2,4-, 3,4-di-, an
Synthesis of 1-deoxyhept-2-ulosyl-glycono-1,5-lactone utilizing α-selective O-glycosidation of 2,6-anhydro-1-deoxy-d-hept-1-enitols
Namme, Rie,Mitsugi, Takashi,Takahashi, Hideyo,Shiro, Moto,Ikegami, Shiro
, p. 9183 - 9192 (2007/10/03)
A series of 1-deoxy-heptulo-2-pyranosyl-glycono-1,5-lactones were synthesized utilizing completely α-selective O-glycosidation of heptenitols. Anomeric configuration of the products was confirmed by 3JC,H coupling measurement and X-ray crystal structural analysis. The benzyl-protected ketosyl saccharides were partly unstable, and glycosidic linkage was prone to cleave under the usual debenzylation conditions. To prevent this, we surveyed various additives for the Pd-catalyzed hydrogenation reaction and found that basic alumina was the most effective.
