A series of novel aminoglycoside oligosaccharide analogs containing a 2,5-dideoxystreptamine core scaffold was prepared to study aminoglycoside binding to the small subunit of 16S rRNA. A set of monosaccharide building blocks carrying amino groups in diff
Efficient routes to glucosamine-myo-inositol derivatives, key building blocks in the synthesis of glycosylphosphatidylinositol anchor substances

Short synthetic routes to protected derivatives of 2-amino-2-deoxy-α-D-glucopyranosyl-(1→6)-D-myo-inositol are described. Various 2-azido-2-deoxy-glucosyl donors were synthesized, starting from D-glucal or glucosamine hydrochloride. Derivatives of 1,2- and 2,3- D-myo-inositol-camphanylidene acetals were prepared to function as glycosyl acceptors. The subsequent glycosylations produced useful building blocks for the synthesis of GPI-anchor substances.

A full account on a total synthesis of GPI anchor 1 employing butanediacetal (BDA) groups and a chiral bis(dihydropyran) is presented. The reactivity of selenium and thio glycosides was tuned by the use of BDA groups. This allowed the assembly of an appro
Synthesis of part of a proposed insulin second messenger glycosylinositol phosphate and the inner core of glycosylphosphatidylinositol anchors

Synthesis of 6-O-(2-amino-2-deoxy-α-D-glucopyranosyl)-D-myo-inositol 1-phosphate, an inner core structure found in various glycosylphosphatidylinositols, and the corresponding 1,2-cyclic phosphate, proposed as part of an insulin second messenger glycosylinositol phosphate, is described. Chirality in the inositol part of the molecule was achieved by the use of a known D-camphor acetal intermediate. The glycosylation used 4-O-allyl-2-azido-3,6-di-O-benzyl-2-deoxy-α-D-glucopyranosyl fluoride as glycosyl donor. The allyl group can be chemoselectively removed, opening a route to oligosaccharides bound to the 4-position of the glucosamine unit. The phosphorylation was accomplished by the phosphoramidate procedure.
Synthesis of the methyl glycosides of a tri- and a tetra-saccharide related to heparin and heparan sulphate

The methyl glycoside of a tetrasaccharide isolated from heparin, methyl O-(α-L-idopyranosyluronic acid)-(1 → 4)-O-(2-acetamido-2-deoxy-α-D-glucopyranosyl)-(1 → 4)-O-(β-D-glucopyranosyluronic acid)-(1 → 3)-O-β-D-galactopyranoside disodium salt and a trisaccharide derivative thereof, methyl O-(α-L-idopyranosyluronic acid)-(1 → 4)-O-(2-acetamido-2-deoxy-α-D-glucopyranosyl)-(1 → 4)-O-β-D-glucopyranosyluronic acid disodium salt, were synthesized using a block-type strategy. A suitable protected disaccharide block of iduronic acid and glucosamine (IdoA-GlcN) was used as a key intermediate for the syntheses and was glycosidated with a protected galactose derivative and a disaccharide block of glucuronic acid and galactose (GlcA-Gal) to give tri- and tetra-saccharide derivatives, respectively. Deprotection gave the target compounds.
