SYNTHESIS OF THE O-SPECIFIC POLYSACCHARIDE OF SHIGELLA FLEXNERI

Kotchekov, N. K.,Byramova, N. E.,Tsvetkov, Yu. E.,Backinowsky, L. V.

, p. 3363 - 3375 (1985)

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.
