  Total Synthesis of theEscherichia coliO111O-Specific Polysaccharide Repeating Unit

  摘要：

  AbstractThe first total synthesis of the O‐antigen pentasaccharide repeating unit from Gram‐negative bacteria Escherichia coli O111 was achieved starting from four monosaccharide building blocks. Key to the synthetic approach was a bis‐glycosylation reaction to combine trisaccharide 10 and colitose 5. The colitose building block (5) was obtained de novo from non‐carbohydrate precursors. The pentasaccharide was equipped at the reducing end with an amino spacer to provide a handle for subsequent conjugation to a carrier protein in anticipation of immunological studies.
