Novel Chiral Ligands and Their Metal Complexes Based on Substituted Imidazolylpyridines

Popis výsledku v původním jazyce

In recent years, it intensively increases development of synthesis and characterisation of new chiral ligands and their transition metal complexes. These complexes are especially used as a homogeneous catalysts in asymmetric synthesis. Main advantage ofour N,N-bidentate ligands is impossiblity of their racemisation as in case oxazolines. These new ligands were prepared analogous to 2,6-bis(4-isopropyl-4-methyl-4,5-dihydro-1H-imidazol-5-on-2-yl)pyridines described in our previous paper, from optically pure 2-amino-2,3-dimethylbutanamides and ethyloxycarbonyl pyridine 2-carboxylic acid, followed by subsequent ring closure reaction giving 4,5-dihydro-1H-imidazol-5-one. The last step was N-alkylation of 4,5-dihydro-1H-imidazol-5-one by different alkylation agents. Ligands prepared in this way were characterised using 1H and 13C NMR spectroscopy. Finally were prepared complexes of ligands with cobalt(II) and copper(II) salts, which structures were confirmed by X-ray diffraction. These meta
