Synthesis of blocked trisaccharide analogue related to the repeating unit of the o-antigen form e. Coli: 025

Methyl 2-O-benzoyW, frO-benzylidene-O-a-D-glucopyranoside 1 was condensed with rhamnose-1-thio donor 2 in the presence of NIS/TMSOTf to yield the disaccharide methyl 2,3,4-tri-0-acetyl-0-α-L-rhamnopyranosyl-(l-3)-2-0- benzoyl-4,6-O-benzylidene-O-α-o-gluco

Synthesis and nmr characterisation of methyl mono- and DI-0-α-L-rhamnopyranosyl-α-d-glucopyranosiduronic acids

The synthesis and NMR characterisation of methyl mono- and di-O-α-L-rhamnopyranosyl-α-D-glucopyranosiduronic acids 1-6 are described. Two commercial starting products were used: methyl α-D-glucopyranoside 7 for the preparation of 1 and 2, and methyl (R)-4,6-O-benzylidene-α-D-glucopyranoside 8 for 3-6. Oxidation reaction of the hydroxymethyl group of glucose to a carboxylic acid group was performed by sodium hypochlorite 2,2,6,6-tetramethyl-1-piperidinyloxy (TEMPO)-mediated procedure after the coupling reaction. Glycosylation was carried out using the trichloroacetimidate approach with trimethylsilyl trifluoromethanesulfonate (TMSOTf) as promoter, resulting in a completely stereoselective formation of the a glycosyl linkage.

Synthesis and Taste of Flavanone and Dihydrochalcone Glycosides Containing 3-O-α-L-Rhamnopyranosyl-D-glucopyranose or 4-O-α-L-Rhamnopyranosyl-D-glucopyranose in the Sugar Moiety

In order to clarify the relationships between the taste and chemical structures of naringin, neohesperidin and their dihydrochalcone (DHC) derivatives, the following glycosides were synthesized.Naringenin 7-O-(3-O-α-L-rhamnopyranosyl-β-D-glucopyranoside)
