The invention relates to methods for producing substituted acrylic acid esters and to the use of the latter for producing substituted γ-amino acids, such as gabapentin and pregabalin. The substituted acrylic acid esters are produced by Wadsworth-Emmons olefination with trialkyl phosphonoacetate in the presence of alkali carbonate as the base, in an aqueous solvent.
