35. According to a definition proposed by Brønsted in 1923, bases are compounds that are able to accept a hydrogen ion: J. N. Brønsted, Recl. Trav. Chim. Pays-Bos 1923, 42, 718.
36. This scenario parallels "ligand-accelerated catalysis" (LAC). By combining the proton (stemming from the Brønsted acid) and the (catalytically inactive) chiral molecule, an equilibrium mixture results in which the active catalyst formed consists of a proton bound to a chiral ligand; for a review on LAC, see: D. J. Berrisford, C. Bolm, K. B. Sharpless, Angew. Chem. 1995, 107, 1159; Angew. Chem. Int. Ed. Engl. 1995, 34, 1059.

41. Reference [11c] gives an excellent background to the current studies and highlights the many contributions published by other researchers, which finally led to the development of the present asymmetric acid-base catalysts; for further details, this review is highly recommended.
42. 2-symmetric bis(amidinium) catalyst was demonstrated: S. B. Tsogoeva, G. Dürner, M. Bolte, M. W. Göbel, Eur. J. Org. Chem. 2003, 1661. In both studies, however, the turnover numbers of the catalysts as well as the enantioselectivities were low or moderate at best.

44. The salts were prepared by first reacting diamine 9a with excess (> 2 equiv) TfOH. The resulting diammonium salt was then mixed with an additional equimolar amount of diamine 9a to yield the desired amine-acid of composition 15. Any variation of this ratio resulted in a decrease of the reaction rate. For example, a salt with a 1:2 (amine/acid) stoichiometry did not show any catalytic activity.

53. A protonated chiral pyrrolidine has also been used in catalyzed asymmetric epoxidations. In this case, however, it appears to only serve as carrier and activator of the peroxymonosulfate anion, and no additional interaction with the olefinic substrate has been described: V. K. Aggarwal, C. Lopin, F. Sandrinelli, J. Am. Chem. Soc. 2003, 125, 7596, and references therein.

55. The authors report that the use of the chiral ligand alone furnished a result comparable to the uncatalyzed reaction (less than 5% yield at -20°C after 5 days).
