The first enantioselectiveorganocatalyticalkylation of electron-rich benzene rings with α,β-unsaturated aldehydes has been accomplished. The use of iminium catalysis has provided a new strategy for the enantioselective construction of benzylic stereogenicity, an important chiral synthon for natural product and medicinal agent synthesis. The (2S,5S)-5-benzyl-2-tert-butylimidazolidinone amine catalyst
