Conclusions
-
1.
O-α-L-Rhamnopyranosyl-1,2-O-cyanoethylidene-β-L-rhamnopyranoses have been synthesized by glycosylation of 1,2-O-cyanoethylidene-β-L-rhamnopyranose deriviatives.
-
2.
The synthesis has been effected of a functionalized disaccharide for the construction of the tetrasaccharide monomer and its polycendensation in order to obtain the O-antigenic polysaccharide of the bacteriumSh. flexneri.
