Abstract: Pyridine-alkoxide (pyalk) ligands that support transition metals have been studied for their use in electrocatalytic applications. Herein, we used the pyalk proligands diphenyl(pyridin-2-yl)methanol ([H]PhPyalk, L1), 1-(pyren-1-yl)-1-(pyridin-2-yl)ethan-1-ol ([H]PyrPyalk, L2), 1-(pyridine-2-yl)-1-(thiophen-2-yl)ethan-1-ol ([H]ThioPyalk, L3), and 1-(ferrocenyl)-1-(pyridin-2-yl)ethan-1-ol ([H]FePyalk, L4) to synthesize CuII complexes that vary in nuclearity and secondary coordination sphere. Also, the proligand 1-(ferrocenyl)-1-(5-methoxy-pyridin-2-yl)ethan-1-ol ([H]FeOMePyalk, L5) was synthesized with a substituted ; however, the isolation of a CuII complex ligated by L5 was not possible. Under variable reaction conditions, the pyalk ligands reacted with CuII precursors and formed either mononuclear or dinuclear CuII complexes depending on the amount of ligand added. The resulting complexes were characterized by single crystal X-ray diffraction, elemental analysis, and cyclic voltammetry.

62 % ee With C39H33N3O2*2ClH In methanol; water at 20℃; for 72 h; General procedure: To a 5 mL vial equipped with a magnetic stirrer bar were added 3-cyclohexyl-2-oxopropanoic acid (1j) (0.0510 g, 0.30 mmol), 2,2-diphenylglycine (2) (0.0681 g, 0.30 mmol), chiral pyridoxamine 6g (0.0195 g, 0.030 mmol), and MeOH-H2O (8:2) (3.0 mL). The mixture was stirred at 20 °C for 3 days. The reaction mixture was transferred to a 25 mL round-bottom flask and MeOH was added until all the solid was dissolved. Then silica gel (0.50 g) was added. After removal of the solvent in vacuo at 20 °C, the resulting residue was submitted to column chromatography on silica gel (EtOH/ethyl acetate/25-28percent ammonia solution =100:58:16) to give compound 3j (0.0401 g, 78percent yield, 52percent ee) as a white solid. The enantiomeric excesses of 3b-k were deteremined by HPLC analysis after being converted to N-benzoyl methyl esters by treatment with thionyl chloride in methanol and subsequent reaction benzoyl chloride.7 The enantiomeric excess of 3a was deteremined by HPLC analysis after being converted to its methyl ester by treatment with CH2N2 in methanol.
