Two novel chiral biphenyl iminium salts derived from L-acetonamine, containing electron-withdrawing 3,3'-substituents on the biphenyl unit, have been prepared and tested as asymmetric catalysts for epoxidation of prochiral alkenes. The results are compared with those achieved using the corresponding unsubstituted system. (c) 2012 Elsevier Ltd. All rights reserved.
