The research details an investigation into the oxidation of cellobiose, maltose, and 4-O-methyl-D-glucose using 2-anthraquinonesulfonic acid (AMS) in sodium hydroxide. The purpose of the study was to gain insights into the reactions of aldoses, specifically aldos-2-uloses, by subjecting these 4-O-substituted aldoses to oxidation conditions similar to those used for D-glucose. The research concluded that the oxidation products included erythronic, arabinonic, ribonic, gluconic, and mannonic acids, as well as 2-C-carboxypentoses, which were identified as a new type of product in the reaction mixture. The study also found that the nonsubstituted products of the reducing D-glucose unit consisted of formic, glycolic, 2-deoxytetronic, and 3-deoxypentonic acids, along with 2-C-carboxy-3-deoxypentoses. The chemicals used in the process included 2-anthraquinonesulfonic acid as the oxidizing agent, sodium hydroxide to maintain the reaction conditions, and various sugars as substrates for the oxidation reactions.
