Chemical approach for the syntheses of GM4 isomers with sialic acid to non-natural linkage positions on galactose

Cell-surface glycans containing sialic acid are involved in various biological phenomena. However, the syntheses of GM4 derivatives with (2→2) and (2→4) linkages have not been investigated to date. In this study, sialylation of all of the hydroxyl groups on galactose were investigated for the syntheses of GM4 isomers. Regioselective sialylation was achieved via protection of galactosyl acceptors using electron-rich benzyl groups. These synthetic sialylated glycans will prove to be useful tools for studying unidentified carbohydrate-mediated biological roles.

Diastereoselective Bromination of Allyl Glycosides Using Tetrabutylammonium Tribromide

Both (R) and (S)-2,3-dibromo-1-propanol with e.e. up to 60percent have been obtained by diastereoselective addition of Br2 to allyl glucosides and galactosides having only one unprotected hydroxyl group at C-2 or C-6 using tetrabutylammonium tribromide, followed by hydrolysis.The absolute configuration is shown to depend on the position of the free hydroxyl and on the configuration at the anomeric centre.
