The reason for choosing this system for study was because of the interesting, experimentally observed correlation of change in enantioselectivity with the change in additive, in this particular case. This provided us with an opportunity to validate the hypothesis presented in the current work with experiment, and our calculations show that indeed the role of the additive, as proposed here, provides perfect correlation with experiment. The current work, therefore, provides important new insights into the rapidly growing area of additive influenced asymmetric organocatalysis.
