Biswas, Sayantan; Ghotekar, Balasaheb K.; Kulkarni, Suvarn S. published the artcile< Total Synthesis of the All-Rare Sugar-Containing Pentasaccharide Repeating Unit of the O-Polysaccharide of Plesiomonas shigelloides Strain 302-73 (Serotype O1)>, HPLC of Formula: 34637-22-4, the main research area is aminosugar bacillosamine fucosamine pneumosamine oligosaccharide preparation stereoselective glycosylation catalyst; oligosaccharide aminoglycoside pentasaccharide repeating unit polysaccharide Plesiomonas shigelloides.
First total synthesis of the conjugation-ready pentasaccharide repeating unit of Plesiomonas shigelloides strain 302-73 (serotype O1) is reported. The complex target pentasaccharide is composed of all-rare amino sugars such as orthogonally functionalized D-bacillosamine, L-fucosamine, and L-pneumosamine linked through four consecutive α-linkages. The poor nucleophilicity of axial 4-OH of L-fucosamine and stereoselective glycosylations are the key challenges in the total synthesis, which was completed via a longest linear sequence of 27 steps in 3% overall yield.
Organic Letters published new progress about Amino sugars Role: RCT (Reactant), SPN (Synthetic Preparation), RACT (Reactant or Reagent), PREP (Preparation). 34637-22-4 belongs to class esters-buliding-blocks, and the molecular formula is C11H15NO3, HPLC of Formula: 34637-22-4.
