The cobalt(II) complex catalysts A, B and a series of complexes C (C, C', C-OEt, and C-O(c)Pen) were prepared from the optically active 1,2-diphenyl-1,2-ethylenediamine, 1,2-bis(3,5-dimethylphenyl)-1,2-ethylenediamine, and 1,2-bis(2,4,6-trimethylphenyl)-1,2-ethylenediamine, respectively

    • Manganese(III) chloride catalyst with the β-ketoimine C'-ligand and Jacobsen's cobalt(II) catalyst afforded the product with very low ee, although β-ketoiminato C' cobalt(II) catalyst and Jacobsen's manganese(III) chloride catalyst were very efficient on the reaction. Therefore, the combination of the center metal and the chiral ligand is essential for the highly enantioselective reduction of 2-phenacylpyridine.
