We also found the oxazolidinone intermediate formed by reaction between the dimer of propionaldehyde, which is formed by the parallel dimerization of propionaldehyde, and the proline catalyst. This intermediate can also contribute to the kinetic resolution of the amino acid catalyst

Most recently, Mauksch, Tsogoeva and co-workers reported that the amino acid derivative formed from the proline-catalyzed reaction between acetone and imine 2 can catalyze its own formation. The reaction exhibits no non-linear effects: M. Mauksch, S. B. Tsogoeva, I. M. Martynova, S. Wei, Angew. Chem. Int. Ed. 2007, 46, 393.
