A new synthetic strategy, which allows to synthesize both α- and β-anomers of 2-acetylaminoglycosyl phosphonate or exclusively β-anomer is described. The present strategy is a successful Michael-type addition of dimethyl hydrogen phosphonate to 2-nitroglycals. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
