THE REACTION OF 2-AMINO-2-DEOXYHEXOPYRANOSES WITH ISOCYANATES. SYNTHESIS OF UREAS AND THEIR TRANSFORMATION INTO HETEROCYCLIC DERIVATIVES.

The reactions of 2-amino-2-deoxyglycopyranoses with aryl isocyanates have been investigated in detail and ureas and heterocyclic derivatives are obtained.The mechanism of formation of glycofurano<2,1-d>imidazolidin-2-ones 62 has now become visible, while previous reports and the classical literature dealing with the subject in question proposed alternative structures for the reaction products.The reactions are pH-dependent and only furanoid bicycles are smoothly obtained at acidic pH values, whereas in neutral or basic media 5-hydroxyimidazolidin-2-one derivatives 66 can be isolated.These monocyclic structures appear to be the true intermediates of the reaction and, under appropriate conditions, can be converted exclusively into the corresponding cis fused five-membered ring systems.Likewise, the first cis-fused glycopyrano<2,1-d>imidazolidin-2-ones 75 have been also prepared.

CHEMISTRY OF BACTERIAL ENDOTOXINS. PART 3. REACTIONS OF OXAZOLINES DERIVED FROM 1,3,4,6-TETRA-O-ACETYL-2<(3R)-3-HYDROXYTETRADECANAMIDO>-Beta-D-GLUCOPYRANOSE

In acidic medium the oxazoline derived from 2-<(3RS)-3-acetoxytetradecanamido>-1,3,4,6-tetra-O-acetyl-2-deoxy-beta-D-glucopyranose readily eliminates elements of acetic acid: it is transformed into an oxazoline that carries an olefinic substituent having the E configuration; this compound, when treated with an alcohol, yields the corresponding beta-D-glucosaminide.No elimination takes place with the analogous 3-hydroxy- or 3-benzyloxy-tetradecanamidoglucosamine derivatives. (3R)-3-benzyloxy-tetradecanoic acid was obtained in 60percent yield upon treatment of methyl (3R)-3-hydroxytetradecanoate in benzene with benzyl bromide, silver oxide, and anhydrous calcium sulphate, followed by saponification.Under similar conditions 3,4,6-tri-O-acetyl-1,2-dideoxy-4′,5′-dihydro-2-<(2R)-2-hydroxytridecyl>-alpha-D-glucopyranoso<2,1-d>oxazole was transformed into the corresponding (2R)-2-benzyloxyoxazoline.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 10034-20-5, you can also check out more blogs about10034-20-5

HF-Induced Intramolecular C-Arylation and C-Alkylation/Fluorination of 2-Aminoglycopyranoses

Internal C-aryl and C-alkyl glycosides derived from 2-aminoglycopyranoses have been synthesized, exploiting a HF-mediated stereoselective intramolecular glycosylation. These conditions are compatible with acetate protecting groups and allow introduction of aromatics with various electronic distributions at the anomeric position. This strategy also provides straightforward entry to original fluorinated sugar-azacycle hybrids via a tandem internal C-glycosylation/fluorination reaction starting from 2-N-allyl/propargyl glycopyranoses. All cyclizations proceed in a 1,2-cis stereocontrolled manner.

O- and N-sulfations of carbohydrates using sulfuryl imidazolium salts

(Chemical Equation Presented) A series of sulfuryl imidazolium salts (SISs) were prepared and examined as reagents for incorporating trichloroethyl- protected sulfate esters into carbohydrates. The SIS that contained a 1,2-dimethylimidazolium moiety (SIS 9) proved to be a superior sulfating compared to SISs bearing no alkyl groups or bulkier alkyl groups on the imidazolium ring. Difficult O-sulfations that required prolonged reaction times and a large excess of the SIS bearing a 1-methylimidazolium group (SIS 5) were achieved in high yield using less than half the amount of SIS 9 in less time. Certain N-sulfated compounds that were practically inaccessible using SIS 5 were obtained in excellent yield using SIS 9.
