Latest Patents

Irène Lehmann holds a patent for a method for the preparation of beta-substituted gamma-amino carboxylic acids. This invention relates to the preparation of β-substituted γ-amino carboxylic acids, preferably in enantiomerically enriched or even enantiomerically pure form. The process involves a one-pot conversion of a β-substituted γ-nitro dicarboxylic acid ester or a β-substituted γ-nitro dicarboxylate to a β-substituted γ-nitro carboxylic acid, followed by the reduction of the γ-nitro group to an amine group. Notably, this invention includes the preparation of (S)-pregabalin, along with the formation of enantiomerically enriched β-substituted γ-amino carboxylic acids and β-substituted γ-nitronate carboxylic acid salts. She has 1 patent to her name.
