Enantioenriched β-functionalized-γ-amino alcohols were produced from simple achiral enals in one flask by combining dienamine- and iminium-catalyzed intermolecular reactions. Reaction products are precursors of γ-amino acids, γ-lactams, and pyrrolidines; one was employed in a synthesis of γ-amino acid (S)-vigabatrin, the bioactive enantiomer of Sabril.
