Abstract: 1-Deoxy-1-nitroalditols can be readily obtained by one-pot reaction of aldoses with nitromethane in aqueous methanol in the presence of a strongly basic anion-exchange resin in the OH^- form and subsequent transformation of the resin into the HCO₃^- form with dry ice. All D-pentoses and six available D-hexoses gave moderate to high conversions (48-91 %) to the nitroaldol products, mostly both epimeric 1-deoxy-1-nitroalditols, in some cases accompanied by tautomeric 2,5- and 2,6-anhydro-1-deoxy-1-nitroalditols . Both types of the strongly basic anion-exchange resins used, R-CH₂N⁺Me₃ OH^- and R-CH₂N⁺Me₂(CH₂CH₂OH) OH^- showed comparable catalytic efficiency. Examples of preparation of 1-deoxy-1-nitro-L-mannitol and -L-glucitol as well as L-mannose and L-glucose show a practical application of the procedure.
