A Three-Component, One-Pot, Sequential Synthesis of a Common Tetrasaccharide Block Related to the Lipopolysaccharide of the Escherichia Coli O9, Klebsiella pneumonia O3, and Hafnia alvei PCM 1223
[摘要]:An expeditious three-component, one-pot, sequential synthesis of a common block tetrasaccharide fragment Manp(1 -> 3)-Manp-(1 -> 2)-Manp-(1 -> 2)-Manp related to the pentasaccharide repeating unit of the O-antigen of Escherichia Coli O9, Klebsiella pneumonia O3, and Hafnia alvei PCM 1223 with minimal protecting group manipulation is reported.
