A new class of Cinchona alkaloid-derived quaternary ammonium phase-transfer catalysts bearing a N-anthracenylmethyl function ate presented. These catalysts show high stereocontrol in the asynunetric alkylation of a benzophenone-derived glycine-imine, and application of this process to the enantiosel
