Synthesis of the Trisaccharide Repeating Unit of the O‐Antigen Related to the Enterohemorrhagic<i>Escherichia coli</i>Type O26:H

Abstract

l‐Fucose was converted to the 2‐azido‐2‐deoxy‐l‐fucose derivative, which together with the monosaccharide synthons prepared from l‐rhamnose and d‐glucosamine hydrochloride were utilized for the synthesis of the p‐ethoxyphenyl glycoside of the trisaccharide repeating unit of the antigen from enterohemorrhagic Escherichia coli type O26:H.
