Abstract:	A regular heteropolysaccharide built of tetrasaccharide repeating units is synthesised by means of regio- and stereospecific polycondensation of a 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.
