A novel sulfated β(1→6)-linked oligosaccharidemimetics has been synthesized and found to be a potent inhibitor of HIV replication, with an IC50 of 1 μM.
Carbonucleotoids (phosphate-bond linked carbohydrates) and carbopeptoids (peptide bond linked carbohydrates) are proposed as new oligosaccharide ligands. The ready access to these analogues is demonstrated by the facile synthesis of the tetrameric carbonucleotoid 1.
Efficient synthesis of carbopeptoid oligomers: insight into mimicry of β-peptide
access to a new class of carbohydrate mimetics was demonstrated by the synthesis of tetrameric carbopeptoids, in which glycosidic bonds were replaced with amide linkages. We herein describe the detailed synthetis method of β(1→2)- and β(1→6)-linked carbopeptoids starting from each d-glucosamine and d-glucose derivative. The buildingblocks were polymerized using BOP reagent and DIEA to form a homooligomer

Abstract 2,6-Anhydroaldonic acids were obtained by oxidation of the corresponding anhydrodeoxynitroalditols (glycopyranosylnitromethanes) with hydrogen peroxide in alkaline solution. Purification was achieved via the methyl anhydroaldonates. The syntheses of five 2,6-anhydrohexonic and eight 2,6-anhydroheptonic acids were accomplished in yields of 44–81%. All corresponding unprotected and acetylated
