This result is in accordance with the work of Singh et al. (see Ref. [4]), who reported higher enantioselectivities at a decreased amount of 0.5 mol% of organocatalyst (S,S)- 3, although such a significant discrepancy in the enantioselectivities was not observed (e.g., for the aldol reaction with 3-chlorobenzaldehyde at room temperature: 0.5 mol%: 97% ee after 5 h; 10 mol%: 86% ee after 2 h). An influence of the thermodynamic control on the asymmetric amplification of a proline-catalyzed aldol reaction has been additionally reported in:, M. Klussmann, H. Iwamura, S. P. Mathew, D. H. Wells, U. Pandya, A. Armstrong, D. G. Blackmond, Nature 2006, 441, 621-623.

In addition, organocatalysts of this type have been mostly postulated as monomeric species so far (see Ref. [4c]), which also is in contrast to explanation option (2). An example of a dimeric organocatalyst is, however, described in:, S. Rho, S. H. Oh, J. W. Lee, J. Y. Lee, J. Chin, C. E. Song, Chem. Commun. 2008, 1208-1210.
