On the big screen: A chiralbiphenol catalyst screening protocol was developed for the rapid identification of enantioselective nucleophilic boronate reactions with acylimines (see scheme). The approach successfully identified a unique catalyst for the reaction of aryl, vinyl, and alkynyl boronates. Mechanistic studies demonstrate boronate ligand exchange with the catalyst is necessary for activation
