In fact, for such good discriminations the logarithmic formula to calculate E can give bizarre values approaching infinity. It therefore makes no sense to give E values of greater than around 100-200 as a change in determined ee or conversions of less than 0.1% have a dramatic influence on the calculated E value.

The ee determination of 11d was difficult due to the peak shape of the second eluting minor enantiomer on HPLC. The ee was, therefore, conservatively estimated which results in an E of "only" 50.
