  Synthesis of the unique trisaccharide repeating unit, isolated from lipopolysaccharides Rhizobium leguminosarum bv. trifolii 24, and its analogue

  摘要：

  The synthesis of trisaccharide: 6-d-alpha-L-Talp(1-->2)-alpha-L-Rhap(1-->5)-DHA, and its analogue: 6-d-alpha-L-Talp(1-->2)-beta-L-Rhaf(1-->5)DHA is described. In the first step a disaccharide, composed of 6-d-L-Talp and L-Rhap was obtained. This, in turn, was converted to the corresponding 1-trichloroacetimidate and coupled with DHA alcohol to afford the required trisaccharide. Its analogue was achieved by the conversion of the above disaccharide to the glycosyl bromide, involving the rhamnopyranose ring scission, followed by condensation with DHA in Koenigs-Knorr procedure.

Both α-O-fucosyl-l-threonine and α-O-fucosyl-(1R,2R)-2-aminocyclohexanol were found to be effective templates for the chemical/enzymatic synthesis of SLex mimetics, and some fucopeptides prepared were 5−10 times more active than SLex as

  The two reagents: 2-trimethylsilyl- and 2-[bis(2,2,2-trifluoroethoxy)phosphoryl]-1,3-dithianes were engaged in the construction of appropriate ketene thioacetals from the isomeric 2-deoxy-hexono-1,5-lactones via Horner-Emmons or Peterson reaction. A comparison of the results shows that the second reagent is more promising, as it forms the desired ketene thioacetals as sole products. The latter were
