Two kinds of chiral C2-symmetric 2,5-disubstituted pyrrolidine derivatives having a β-aminoalcohol moiety have been successfully synthesized and their catalytic abilities of chiral induction have been examined in the reactions of diethylzinc with arylaldehydes. The production of sec-alcohols having R-absolute configuration could be achieved in very high chemical yield (85–95%) and very high enantiomeric
