Abstract : D-Glucosone (D-arabino-hexosulose), on treatment with alkali, gives a mixture of acids, consisting largely of mannonic, gluconic, arabinonic, ribonic and erythronic acids. The stereoselective rearrangement into mannonic acids is the main reaction with calcium hydroxide and the cleavage yielding arabinonic acid is the main reaction with sodium hydroxide. The similarity in reaction products obtained when glucose is treated with aqueous sodium polysulphide and when glucosone is treated with aqueous sodium hydroxide strongly supports the hypothesis that glucosone is an intermediate in the former reaction.
