Synthesis of l-iduronic acid containing a common pentasaccharide repeating unit related to Escherichia coli O112ab and Shigella boydii serotype B15.
Synthesis of an l-iduronic acid-containing identical O-antigenic pentasaccharide repeating unit related to the cell wall of E. coli O112ab and Shigella boydii serotype B15 has been successfully accomplished in satisfactory yield. The protected pentasaccharide was obtained via an efficient, stereoselective [2 + 3] block...
