Convergent synthesis of an octasaccharide fragment of the O-specific polysaccharide of Shigella dysenteriae type 1

A stereocontrolled, convergent synthesis is described of the linear octasaccharide methyl glycoside α-L-Rhap-(1 -> 2)-α-D-Galp-(1 -> 3)-α-GlcpNAc-(1 -> 3)-α-L-Rhap-(1 -> 3)-α-L-Rhap-(1 -> 2)-α-D-Galp-(1 -> 3)-α-D-GlcpNAc-(1 -> 3)-α-L-Rhap-OMe (11), which

SYNTHESIS OF THE O-SPECIFIC POLYSACCHARIDE OF SHIGELLA FLEXNERI

A regular heteropolysaccharide built of tetrasaccharide repeating units is synthesised by means of regio- and stereospecific polycondensation of tritylated cyanoethylidene derivative.The polysaccharide obtained is identical with the O-antigenic polysaccharides of Shigella flexneri serotypes 3b, 3c, and variant Y.It also represents the basic chain of O-antigenic polysaccharides of all serotypes of this bacterium.

ARTIFICIAL CARBOHYDRATE ANTIGENS: A BLOCK SYNTHESIS OF A LINEAR, TETRASACCHARIDE REPEATING-UNIT OF THE Shigella flexneri VARIANT Y POLYSACCHARIDE

Glycosylation of methyl 2,4-di-O-benzoyl-α-L-rhamnopyranoside with 2,3,4-tri-O-acetyl-α-L-rhamnopyranosyl bromide gave methyl 2,4-di-O-benzoyl-3-O-(2,3,4-tri-O-acetyl-α-L-rhamnopyranosyl)-α-L-rhamnopyranoside (4) in 93percent yield.Conversion of 4 into th
