title: Convergent synthesis of an octasaccharide fragment of the O-specific polysaccharide of Shigella dysenteriae type 1.
abstract: A stereocontrolled, convergent synthesis is described of the linear octasaccharide methyl glycoside alpha-L-Rha p-(1-->2)-alpha-D-Gal p-(1-->3)-alpha-Glc p NAc-(1-->3)-al pha-L-Rha p-(1-->3)-alpha-L-Rha p-(1-->2)-alpha-D-Gal p-(1-->3) -alpha-D-Glc p NAc-(1-->3)-alpha-L-Rha p-OMe (11), which corresponds to two contiguous repeating units of the O-specific polysaccharide of Shigella dysenteriae type 1.
