An enantioselective synthesis of (2S,3R)-piperidine-2,3-dicarboxylic acid and (2S,3S)-piperidine-2,3-dicarboxylic acid is described. This synthesis was mainly based on a δ-amino acid formation via a domino reaction: allylic acetate rearrangement, stereoselective Ireland-Claisen rearrangement and asymmetric Michaeladdition protocol from a Baylis–Hillman adduct, in which the cinnamaldehyde double bond
