Abstract

The present invention relates to the preparation of β-substituted γ-amino carboxylic acids, preferably in enantiomerically enriched or even enantiomerically pure form, by a one-pot conversion of a β-substituted γ-nitro dicarboxylic acid ester or of a β-substituted γ-nitro dicarboxylate of general formula to a β-substituted γ-nitro carboxylic acid and a subsequent reduction of the γ-nitro group to an amine group. In particular, the present invention relates to the preparation of (S)-pregabalin. In addition, the formation of enantiomerically enriched β-substituted γ-amino carboxylic acids and β-substituted γ-nitronate carboxylic acid salts are also described.
