Reactions of Saccharides Catalyzed by Molybdate Ions. II.* Epimerization of D-Glucose and D-Mannose
نویسنده
چکیده
In acidified water solutions of molybdate, aldoses epimerize under the formation of equilibrium mixtures in which the epimer having trans relationship of the hydroxyl groups at C-2 and C-3 predominates. The epimerization of both D-glucose and D-mannose gives the equilibrium mixture of D-glucose and D-mannose in the ratio 75 25. A tentative mechanism for this reaction is suggested and the preparation of D-mannose from D-glucose is described.

Reaction Kinetics and Mechanism of the Molybdate-Catalyzed Epimerization of Glucose in Aqueous Solutions Using A Microstructured Reactor
In this research work the reaction kinetics of the molybdate-catalyzed epimerization of glucose in aqueous solutions has been mathematical modeled and investigated. Experiments were performed in a microstructured reactor in continuous flow regime. The results show high yield of mannose in the range between 21-27.1%, which exceeds the actual literature data with a ratio 3:1. The kinetic model is...
متن کاملCatalytic Isomerization of Biomass‐Derived Aldoses: A Review
Selected aldohexoses (D-glucose, D-mannose, and D-galactose) and aldopentoses (D-xylose, L-arabinose, and D-ribose) are readily available components of biopolymers. Isomerization reactions of these substances are very attractive as carbon-efficient processes to broaden the portfolio of abundant monosaccharides. This review focuses on the chemocatalytic isomerization of aldoses into the correspo...

متن کاملOne-Pot Synthesis of (+)-Nootkatone via Dark Singlet Oxygenation of Valencene: The Triple Role of the Amphiphilic Molybdate Catalyst
Efficient one-pot catalytic synthesis of (+)-nootkatone was performed from (+)-valencene using only hydrogen peroxide and amphiphilic molybdate ions. The process required no solvent and proceeded in three cascade reactions: (i) singlet oxygenation of valencene according to the ene reaction; (ii) Schenck rearrangement of one hydroperoxide into the secondary β-hydroperoxide; and (iii) dehydration...
متن کاملThe enzymatic synthesis of thymidine diphosphate glucose and its conversion to thymidine diphosphate rhamnose.
. Studies from several laboratories have shown that labeled glucose is converted to B-deoxy hexoses without randomization of the label when microorganisms are grown on n-glucose-l-C14 or n-glucose-MY4 as the sole source of carbohydrate (l-3). Evidence of this type has been interpreted to indicate a conversion of the intact hexose moiety to the deoxy compound without scission of the hexose carbo...
