  Linear synthesis and conformational analysis of the pentasaccharide repeating unit of the cell wall O-antigen of Escherichia coli O13

  摘要：

  Synthesis of the pentasaccharide repeating unit of the O-antigen of Escherichia coli O13 strain has been achieved using a straightforward linear synthetic strategy. Similar reaction conditions have been used for all glycosylations as well as protective group manipulations. All intermediate steps are high yielding and the glycosylation steps are stereoselective. The synthesized pentasaccharide was subjected to conformational analysis using 2D ROESY NMR spectral analysis and molecular dynamics (MD) simulation to get detailed information on conformation of the molecule in aqueous solution.
