For this reason, the descriptors of choice were ASO for the portrayal of steric information, and ESPmax for the electronic information. These descriptors are more abstract than the ones commonly used when building an MLR model (e.g., NBO charges, cone angles). However, the emphasis of this work is on descriptors that have been previously shown to work well, as opposed to exploring a wide range of descriptors that relate to the reaction mechanism. Therefore, the choice of an SVR model was also appropriate. As mentioned in the section Models, the descriptors appearing in the final SVR model cannot generally be used to gain insights into the reaction mechanism and the factors that influence enantioselectivity. Thus, there is no underlying assumption of a shared mechanism/stereoselective step.
