چکیده

C-linked neuraminic acid disaccharide was synthesized in a diastereoselective manner from a sulfone donor and aldehyde acceptor, which was protected as a propargyl ether, through a samarium-mediated coupling reaction. The resulting disaccharide has acetal and phenyl sulfide functional groups that can be easily converted into aldehyde and phenyl sulfone groups by photolysis and oxidation reactions to serve as disaccharide acceptor and donor, respectively.

Synthesis of nor-C-linked neuraminic acid disaccharide: a versatile precursor of C-analogs of oligosialic acids and gangliosides.

The Neu5Acalpha(2,8)Neu5Ac disaccharide is an important constituent of tumor related antigen, however, the O-linkage is catabolically unstable. Vaccination with a catabolically stable sialic acid C-glycoside analog might enhance immunogenicity. The synthesis of Neu5Ac nor-C-disaccharide 20R/S, corresponding to versatile precursors of C-analogs of oligosialic acid and gangliosides, is reported. ...

A stereodivergent, two-directional synthesis of stereoisomeric C-linked disaccharide mimetics.

Dipyranones, such as 1,2-bis[(2R,3S,6S)-3-hydroxy-6-methoxy-3-oxo-6H-pyran-2-yl]ethane, were exploited as templates for the synthesis of some novel C-linked disaccharide analogues. Efficient methods, such as stereoselective reduction and dihydroxylation, were developed for two-directional functionalisation of these templates. Peracetylated derivatives of ten stereoisomeric disaccharide analogue...

Design and synthesis of unnatural heparosan and chondroitin building blocks.

Triazole linked heparosan and chondroitin disaccharide and tetrasaccharide building blocks were synthesized in a stereoselective manner by applying a very efficient copper catalyzed azide-alkyne cycloaddition (CuAAC) reaction of appropriately substituted azido-glucuronic acid and propargyluted N-acetyl glucosamine and N-acetyl galactosamine derivative, respectively. The resulting suitably subst...

Synthesis of a serine-based neuraminic acid C-glycoside.

Cell-surface carbohydrates are classified by the nature of their linkages to the protein as either N-linked or O-linked. O- and N-glycans are involved in a number of important biological functions. These activities can be lost on glycoprotein catabolism when these glycan linkages are enzymatically hydrolyzed. The design and synthesis of novel C-linked glycans should provide catabolically stable...

Application of Non-Corrosive Acids in Three-Component, One-Pot Synthesis of Commercial Coumarin Dye

The efficiency of HZSM-5 Zeolite, tungestophosphoric acid (H3PW12O40) and tungestosililic acid (H4O40SiW12) were investigated in three-component, one-pot synthesis of coumarin dyes. These green and noncorrosive acids were highly efficient in synthesis of some coumarin dyes in excellent yield during concurrent formation of coumarin and benzimidazole or benzoxazole heterocycles (e.g. C. I. disper...
