The synthesis of the ribosyl-ribitol derivatives and (Scheme 2) is presented. The compounds served as building blocks for the preparation of protected fragments (, n=1 or 2; Fig. 2) of the title polysaccharide. The bifunctional reagent bis[1-benzotriazolyl]-2-chlorophenylphosphate (, Fig. 2) was used for all phosphorylation reactions. Attachment to a spacer and complete deprotection of the products
