Son, Sang-Hyun published the artcileStereoselective tris-glycosylation to introduce β-(1→3)-branches into gentiotetraose for the concise synthesis of phytoalexin-elicitor heptaglucoside, Application of 1-(Phenylsulfinyl)piperidine, the publication is Organic & Biomolecular Chemistry (2008), 6(8), 1441-1449, database is CAplus and MEDLINE.
Dodecyl thioglycosides (3, 4, 5) were prepared by conventional transformation of d-glucose and used as new glycosyl donors for a short-step synthesis of phytoalexin elicitor heptaglucoside. A gentio-tetraoside derivative (6) having three hydroxyl groups was synthesized by NIS-TfOH promoted glycosylate in more than 90% yield followed by selective removal of temporary protective groups. Undesired formation of α-glycosides at the introduction of β-(1→3)-branches into gentio-oligosaccharides was found to be suppressed by use of a thiophilic reagent system, BSP (1-benzenesulfinyl piperidine)-Tf2O, giving the heptaglucoside in only four glycosylation steps.
