The stereoselective Michael addition of pyruvate to β-nitrostyrenes catalyzed by NahE, a type 1 aldolase, is reported. β-Aryl-γ-nitrobutyric acids can be isolated after oxidative decarboxylation in high yields on a preparative scale, providing access to precursors of γ-aminobutyric acid (GABA) analogues of demonstrated pharmacological activity.
