Synthesis of glycosyl phosphates from 1,2-orthoesters and application to in situ glycosylation reactions

A series of glycosyl phosphates were prepared in high yield by treatment of the corresponding 1,2-orthoesters with dibutyl phosphate. Glycosyl phosphates are efficient glycosylating agents even when used in crude form or when generated in situ. The immuno

Blockwise Approach to Fragments of the O-Specific Polysaccharide of Shigella flexneri Serotype 2a: Convergent Synthesis of A Decasaccharide Representative of a Dimer of the Branched Repeating Unit

The D′A′B′(E′)C′DAB(E)C decasaccharide representative of a dimer of a frame-shifted pentasaccharide repeating unit of the O-specific polysaccharide of Shigella flexneri 2a was synthesized as its methyl glycoside by condensing a pentasaccharide donor (D′A′B′ (E′)C′) and a pentasaccharide acceptor (DAB(E)C-OMe). Several convergent routes to these two building blocks, involving either the AB linkage or the BC linkage as the disconnection site, were evaluated in comparison to the linear strategy. The latter was preferred. It is based on the use of the trichloroacetimidate chemistry. The target branched oligosaccharide was designed to probe the recognition at the molecular level of the natural polysaccharide by protective monoclonal antibodies.

Studies on carbohydrates XVIII. Synthesis of tetrasaccharide corresponding to biological repeat units of Serratia marcescens O18 polysaccharide

The synthesis of a blocked tetrasaccharide portion of the biological repeat unit, [→2)L-Rhapα(1→2)L-Rhapα(1→2)L-Rhapα(1→6)D-GlcNAcpα(1→], of the Serratia marcescens O18 polysaccharide was described. The key intermediate compounds was 3,4-blocked -L-rhamno
