Enantioselective conjugate addition of diethylzine to chalcone catalyzed by Co(acac)2 and chiral amino alcohols

Article abstract of DOI:10.1016/S0957-4166(97)00144-4

Co(acac)₂ in the presence of chiral ligands has been employed as catalyst for the enantioselective conjugate addition of diethylzinc to chalcone. With chiral amino alcohols derived from (+)-camphor, enantioselectivities up to 83% were achieved.
