Popis: | The reactions of 4-[(4-formylphenoxy)methyl] derivatives of ethyl 6-alkyl(phenyl)-substituted nicotinates with primary amines, glycols and 1,2-phenylenediamine, leading to the formation of the corresponding azomethines, 1,3-dioxolanes, and 2,3-dihydrobenzylimidazoles with preparative yields were studied. The synthesized azomethines were selectively reduced into the corresponding secondary amines with sodium triacetoxyborohydride in benzene at 20–25°C. The composition and structure of the synthesized compounds was established by elemental analysis and IR and 1H and 13C NMR spectroscopy. |
