An octyl N-acetylglucosaminide derivative with a pentaerythritol chain at position 6 has been synthesized and evaluated as an inhibitor of neural tumor growth. The glycoside inhibited the growth of a neuroectodermic tumor implanted in rats and, when loade
A new synthesis of O-glycosides from totally O-unprotected glycosyl donors
Ferrieres, Vincent
, p. 2749 - 2752 (1995)
O-Glycosidation of the totally O-unprotected aldoses (D-glucose, D-galactose and D-mannose) and D-fructose in THF or 1,4-dioxane using anhydrous FeCl3 as promoter afforded either aldofuranosides 1, 3, 4 in good overall yields or exclusively β-D-fructopyranosides 7. Conversely α-D-aldopyranosides 2, 5 and 6 were obtained respectively from D-glucose, D-mannose and N-acetyl-D-glucosamine when the reactions were performed in the presence of BF3.OEt2 under ultrasonication.
Straightforward glycosylation of alcohols and amino acids mediated by ionic liquid

Green glycosylation of functionalized alcohols and α-amino acids, using an ionic liquid as a recyclable solvent, was performed in one step directly from the unprotected monosaccharide under scandium triflate or ferric chloride catalysis. Pure α- and β-glycosides could be obtained after specific enzymatic hydrolysis.
Ionic liquid promoted atom economic glycosylation under Lewis acid catalysis
Auge, Jacques,Sizun, Gwenaelle
scheme or table, p. 1179 - 1183 (2010/05/02)
Straightforward glycosylation of various alcohols with unprotected and non-activated monosaccharides were performed under scandium triflate catalysis. Rate and yield of glycosylation were highly improved when using 1-butyl-3-methylimidazolium trifluoromethanesulfonate as a green solvent. This ionic liquid was allowed to be recycled at least three times without loss of activity. The possibility of drastically reducing the amounts of catalyst (down to 1 mol%) and aglycone (down to 1 equiv) when performing the reaction in ionic liquid opens new perspectives in O-glycosylation, as a direct coupling between an aglycone and free sugars.
Protecting group free glycosidations using p-toluenesulfonohydrazide donors
Gudmundsdottir, Anna V.,Nitz, Mark
supporting information; scheme or table, p. 3461 - 3463 (2009/04/16)
(Figure Presented) N-Glycopyranosylsulfonohydrazides are introduced as glycosyl donors for protecting group free synthesis of O-glycosides, glycosyl azides, and oxazolines. Mono- and disaccharides containing a reducing terminal N-acelylglucosamine residue were condensed with p-toluenesulfonylhydrazide to give the desired β-D-pyranose donors. These donors can be activated with NBS and then glycosidated with the desired alcohol or transformed to the oxazoline or glycosyl azide.

, p. 364 - 373 (2007/10/03)
An N-acetylglucosaminide derivative with a pentaerythritol substituent at position C-6 was previously synthesized and shown to inhibit neural tumor growth. Now, we report the preparation of a series of new synthetic compounds introducing systematic change

, p. 4599 - 4606 (2007/10/03)
Several α-L-Fuc-(1→3)-α-D-GlcNAcOC8H17 disaccharide derivatives bearing different hydroxylated alkyl chains, with or without sulfate groups at C-4 and/or C-6 positions of the GlcNAc unit, have been synthesized and tested as inhibitor
