Vliegenthart, Identification of 3-deoxy-matmo-2-octulosonic acid, 3-deoxy-5-0-methyl-mawio-2-octulosonic acid and 3-deoxy-/yxo-2-heptulosaric acid in the cell wall (theca) of the green alga Tetraselmis striata Butcher (Prasinophyceae), Eur. J. Biochem., 182 (1989) 153-160. [Pg.57]

Deoxy-i>maw f)-2-octulosonic acid 8-phosphate can be obtained in gram quantities by using KDO synthase (F.C 4.1.2.16) for the addition of PEP to D-arabinose 5-phosphate33. DA HP synthase (EC 4.1.2.15) produces 3-deoxy-L>-arer/>/>io-heptulosonic acid 7-phosphate from PEP and D-erythrose 4-phosphate35. [Pg.593]

These results have been used to prepare key starting compounds 11 and 12 for the enantioselective synthesis of 3-deoxy-D-manno-2-octulosonic acid... [Pg.258]

Several glyculosonic acids have been identified as components of bacterial polysaccharides. D-/yxo-Hexulosonic acid, as Q -D-pyranosyl residues (23), is a component of the extracellular polysaccharide from a Rhodococcus species. The LPS from Acinetobacter calcoaceticus NCTC 10305 contains - D-g/ycero-D-/a/o-octulosonic acid (24). It is isosteric with 3-deoxy-D-mnnno-octulosonic acid (25), which is a constituent of bacterial LPS and links the polysaccharide part to the lipid A region. It seems possible that D-g/ycero-D-tfl/o-octulosonic acid replaces 3-deoxy-D-/wan o-octulosonic acid in the A. calcoaceticus LPS. [Pg.295]

Acyclic dienes react with glyoxylic acid via an oxo-Diels-Alder reaction to give dihydropyran derivatives (Eq. 12.53). An excellent application of the oxo-Diels-Alder reaction is reported by Lubineau et al. in the synthesis of the sialic acids, 3-deoxy-Z)-manno-2-octulosonic acid (KDO) and 3-deoxy-D-glycero-D-galacto-2-nonulosonic acid (KDN).123... [Pg.404]

Upon treatment with n-BruiNF, product 97 is converted to 98, which is a key intermediate for the synthesis of the monosaccharide 3-deoxy-D-manno-2-octulosonic acid (KDO)—an essential constituent of the outer membrane lip-op oly s accharide (LPS) of gram-negative bacteria.40... [Pg.292]

Charon and Szabo17 demonstrated that chromophore 4 may be produced to a significant extent from a 5-O-substituted derivative of KDO (which does not contain a free diol grouping at C-4-C-5). These authors synthesized 3-deoxy-5-0-methyl-2-octulosonic acid (7 configuration at C-5-C-7, arabino at C-4, unknown) by the Comforth reaction18,19 from 4-0-formyl-2-0-methyl-D-arabinose (see Scheme 4 and Section IV,1). Compound 7 gave a millimolar extinction coefficient of 13 in the TBA assay (as compared to 92 5 for KDO). Based on this result, Charon and Szabo17 formulated for the TBA reaction of 5-0-... [Pg.329]
