| Description
| - 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 of our 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 metal complexes were

- Syntéza a charakterizace nových chirálních ligandů a komplexů s přechodnými kovy patří mezi nejvíce se rozvíjející oblasti organické chemie. Tyto komplexy jsou velmi často používány jako enantioselekivní katalyzátory pro asymetrické reakce. Hlavní výhodou našich N,N-bidentátních ligandů oproti oxazolinovým ligandům je to, že nemohou racemizovat. Tyto nové ligandy byly připraveny analogicky jako 2,6-bis(4-isopropyl-4-methyl-4,5-dihydro-1H-imidazol-5-on-2-yl)pyridiny, jejichž syntéza byla popsána v předchozí publikaci z opticky čistých 2-amino-2,3-dimethylbutanamidů a ethyloxykarbonyl pyridin-2-karboxylové kyseliny. Takto připravený acylovaný aminoamid byl cyklizován v bázickém prostředí na příslušné 4,5-dihydro-1H-imidazol-5-ony. V posledním kroku byla provedena N-alkylace 4,5-dihydro-1H-imidazol-5-onů různými alkylačními činidly. Připravené ligandy byly charakterizovány pomocí 1H a 13C NMR spektroskopie. Byly připraveny komplexy těchto ligandů s kobaltem(II) a mědí(II) a byly charakterizovány pomocí r (cs)
