Abstract: Sodium salts of the epimeric 1-deoxy-l-nitrooctitols obtained by nitromethane synthesis with D-glycero-D-galactoheptose were converted by hydrogen peroxide under catalytic action of molybdate ions into D- erythro -L-glucooctose and D- erythro -L-mannooctose. Molybdate-catalyzed epimerization of D- erythro -L-mannooctose led to a mixture of epimeric aldooctoses in which D-erythro-L-glucooctose predominated. The aldooctoses occur in pyranoid structures in aqueous solutions and their complexing with molybdate ions induces furanoid structures.
