| Аннотация |
The conformational properties of three pyridoxine derivatives were studied by 1H dynamic NMR spectroscopy. It was shown that conformational exchange depends on the type of substituents for investigated compounds. Conformational exchange caused by a rotation of substituents around C-C bond was studied for all pyridoxine derivatives by NMR experiments at low temperatures. It was also established that one of the compounds (9-(2,4-dinitrophenoxy)-3,3,8-trimethyl-6-(2-nitrophenyl)-1,5-dihydro-[1,3]dioxepino[5,6-с]pyridine) takes part in additional conformational exchange process associated with a rotation of dinitrophenyl fragment around C-O bond. Conformational transitions between twist forms of the seven-membered acetal cycle were discovered for compounds II and III. Line shape analysis of dynamic NMR spectra allowed determining energy barriers for all observed conformational exchange processes. |
