diverse carbohydrate probes, solution-phase parallel and enzymatic glycosylations were performed. Three model disaccharides were in parallel synthesized in solution-phase and used as carbohydrate probes for the fabrication of carbohydrate chips. Three enzymatic glycosylations on glass slides were consecutively performed to generate carbohydrate microarrays that contained the complex oligosaccharide, sialyl
Sequential one-pot glycosylations among various glycosidic donors (glycosyl bromide, glycosyl trichloroimidate, glycosyl fluoride), a β-thiophenyl glycoside derivative and a α-methyl glycoside derivative have been attempted to give the corresponding trisaccharides.
heptasaccharide 1 having phytoalexin elicitor activity in soybeans by one-pot glycosylation. The synthesis involves chemo- and regioselective sequential six-step glycosylations using seven independent building blocks and sequential removal of acyl- and benzyl ether-type protecting groups. The coupling of seven building blocks requires only four chemoselective activitable leavinggroups of glycosyl donors

One-pot glycosylations of glycosyl bromides and phenylthio glycosides with various dihydroxyl glycosyl acceptors have been examined to provide the corresponding branched trisaccharides.

Mixed Branched-Linear Type One-Pot Glycosylation: Synthesis of Hepta β-D-glucoside
A mixed branched-linear type one-pot glycosylation (OPG), which formed three glycosidic linkages in a single reaction vessel, has been developed. Synthesis of protected hepta β-D-glucoside has been achieved in three steps from monosaccharide building blocks by the OPG.
