This paper reports the rational design, synthesis and biochemical evaluation of a new type of cellulase inhibitor. This isofagomine isomer analogous to the β- l -idopyranose linked to a glucosidic unit by a methylenic bond is able to mimic the pseud

1,6-Anhydro-β- l -hexopyranoses as valuable building blocks toward the synthesis of l -gulosamine and l -altrose derivatives via the regioselective triflation and benzoylation of 1,6-anhydro-β- l -idopyranose followed by SN2 substitution with vario

The synthesis of a heparin-like pentasaccharide, containing 2,6-di-O-sulphated α-L-idopyranose instead of the naturally occurring 2-O-sulphated α-L-idopyranuronate, is described. Although conformational properties of these compounds are similar, th
