Description
Summary:Hepta-O-acetyl-O-α- D -Rhap-(1 → 3)-O-α- D -Rhap-(1 → 2)-glycerol ( 5 ) was the major component derived by way of Smith degradation of A-band polysaccharide (a D -rhamnan isolated from a mutant, AK1401, of Pseudomonas aeruginosa strain PAO1). The structure has been verified by an unambiguous synthesis of 5 . Based on mass spectrometric evidence, hepta-O-acetyl-O-Ribp-(1 → 3)-O-α- D -Rhap-(1 → 2)-glycerol is considered to be one of the minor components. The Smith degradation of A-band polysaccharide and the synthesis of 5 are reported.
