23. 4 is ineffective for these reactions.
24. 4 was used for some entries (see the Supporting Information). Identical results were obtained with 2 for the preparation of the other enantiomers. No effect of the counterion was detected, and the change in counterion between the catalysts types does not affect the stereochemical outcome.
