, p. 297 - 298 (1994)
A chiral catalyst prepared from nickel(II) chloride and chiral β-diamine, (S)-1-pentyl-2-anilinomethylpyrrolidine, was found to be effective for the enantioselective conjugate addition of diethylzinc to chalcones to afford corresponding β-substituted keto

Conjugate addition of diethylzinc to enones is catalyzed by a complex derived from Ni(acac)2 and C2-symmetric 2,2'-bipyridine 3 or chiral pyridines 5-12.The products are obtained with optical purities up to 89percent ee.A strong positive nonlin
