A Purification‐Free Strategy for the Electrochemical Oxidation of the Primary Hydroxy Group in Glycopyranosides

open access: yesChemElectroChem, Volume 12, Issue 18, September 15, 2025.
A straightforward protocol for the electrochemical oxidation of the primary hydroxy group in glycopyranosides is presented. It uses aqueous ammonia as a base and electrolyte, reticulated vitreous carbon (RVC) electrodes, and TEMPO as a mediator. The ammonium salts of the corresponding uronic acids are obtained in excellent yield upon evaporation of the

Synthesis of Uridine Diphosphate-Glucuronic Acid

open access: yesChemical and Pharmaceutical Bulletin, 1960
Uridine 5'-phosphoramidate (I) was allowed to react with α-glucuronic acid 1-phosphate (II), and α-uridine diphosphate glucuronic acid (α-UDPGA) (III) was isolated from the reaction mixture by ion exchange chromatography. Likewise, β-UDPGA (V) was produced from (I) and β-glucuronic acid 1-phosphate (IV).
