Mannopyranosyl Uronic Acid Donor Reactivity

Organic Letters, 2011
The reactivity of a variety of mannopyranosyl uronic acid donors was assessed in a set of competition experiments, in which two (S)-tolyl mannosyl donors were made to compete for a limited amount of promoter (NIS/TfOH). These experiments revealed that the reactivity of mannuronic acid donors is significantly higher than expected based on the electron ...

Automated ion-exchange chromatography of uronic acids and uronic acid containing oligosaccharides

Analytical Biochemistry, 1968
Abstract An automated anion-exchange chromatographic procedure for the separation of uronic acids and uronic acid containing oligosaccharides is described. The method has been applied, in particular, to the separation and quantitation of l -iduronic and d -glucuronic acid in hydrolyzates of dermatan sulfate, and the hydrolysis conditions required ...

A modified uronic acid carbazole reaction

Analytical Biochemistry, 1962
Abstract A modification of Dische's carbazole reaction for uronic acid in the presence of borate is described. The advantages of the procedure are: 1. (1) There is an approximately twofold increase of sensitivity. The OD is a linear function of concentration between 4 and 40 μg/ml. 2. (2) Maximum color develops immediately. 3.

4-Deoxy uronic acids

Carbohydrate Research, 1969
Abstract Starting from the anomers of methyl (methyl D -galactopyranosid)uronate the corresponding Δ 4,5 unsaturated uronic acid derivatives, the anomeric methyl (methyl 4-deoxy- L - threo -hex-4-enopyranosid)uronates, have been prepared by a base-catalyzed elimination reaction.

Identification of uronic acids in mucopolysaccharides

Archives of Biochemistry and Biophysics, 1963
The isolation or identification of uronic acids from acid mucopolysaccharides can be achieved by hydrolysis with formic acid and chromatography of the hydrolyzates.
