A Purification‐Free Strategy for the Electrochemical Oxidation of the Primary Hydroxy Group in Glycopyranosides
Von Wiley-VCH zur Verfügung gestellt
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 volatiles.
