The standard Cahn-Ingold-Prelog (CIP) method for stereoisomer assignment of R or S is not selfconsistent for the library of resultant products from the DAAA reaction, as this assignment is dependent on the identity of the structural units A-D and the added allyl fragment. Therefore, the facial selectivity driven by the Trost ligands would not be accounted for. The enantioselectivity target of this ML analysis was therefore defined as '%topA' or the percentage of the 'top' isomer, as proposed and used elsewhere. This is defined as placing the α-carbonyl to the left of the site of C-allylation and with the aryl unit A pointing up or 'on top'. Therefore a 50 % ee would have a 75% or 25% '%topA', depending on which face the aryl unit is situated on.
