A general strategy for the synthesis of 3,6-branched gluco-oligosaccharides: Facile synthesis of the phytoalexin elicitor oligosaccharides

A general method for the synthesis of 3,6-branched gluco-oligosaccharides has been developed. As a typical example of the method, the synthesis of the glucohexatose phytoalexin elicitor on a large scale was achieved via coupling of a trisaccharide donor with a trisaccharide acceptor. The donor and acceptor were prepared easily from 1,2:5,6-di-O-isopropylidene-α-D-glucofuranose, 2,3,4,6-tetra-O-benzoyl-α-D-glucopyranosyl trichloroacetimidate, and 6-O-acetyl-2,3,4-tri-O-benzoyl-α-D-glucopyranosyl trichloroacetimidate in a regio- and stereoselective manner. Higher oligosaccharides of the elicitor including the hepta-, nona-, dodeca- and tetradecasaccharides have also been readily synthesized by this strategy.

Highly efficient syntheses of the phytoalexin-elicitor active β- (1→3)-branched β-(1→6)-linked heptaglucose and its dodecyl glycoside

A highly efficient method for the synthesis of 3,6-branched gluco-oligosaccharides was developed by using 1,2:5,6-di-O-isopropylidene-α-D-glucofuranose, 2,3,4,6-tetra-O-benzoyl-α-D-glucopyranosyl trichloroacetimidate, and 6-O-acetyl-2,3,4-tri-O-benzoyl-α-
