A novel method for the synthesis of densely functionalized optically active 5-carboxymethyl tetramic acids is reported. The proposed strategy is focused on the synthesis of 3,3′-disubstituted pyrrolidine-2,4-diones as useful molecules for the synthesis of natural products. The proposed methodology has been established by X-ray diffraction structure analysis.
