Abstract

original image

And isn′t it uronic: A mild, highly efficient and selective catalytic oxidation of pectin-derived uronic acids to the corresponding aldaric acids is reported. Fast, quantitative conversions (>99 %) of the starting materials are achieved with high selectivity (>97 %) at room temperature, using supported gold catalysts and air as oxidizing agent.
