A convenient organocatalytic enantioselective decarboxylative Michael addition of β-keto acids to dicyanoolefins and disulfonylolefins is realized. In the presence of saccharide-derived chiral amino thioureas, the reaction proceeded smoothly to afford a wide range of the Michael adducts in 62–99% yield with 70–94% ee. Moreover, one of the chiral adducts obtained could be readily converted into the monofluorinated product in a total 68% yield over four steps with 85% ee. (Figure presented.).

The enantioselective conjugate addition of malononitrile to trans-chalcones has been investigated as a case study using easily available α,α-L-diaryl prolinols as promoters. Both experimental and computational results are consistent with a bifunctional no
