[摘要]：The synthesis of a series of ferrocenyl-substituted 2-aminopyridine- and 6-amino-4,5-dihydropyridine-3,5-dicarbonitriles, 4-aminopyrimidine- and 3,4-dihydropyrimidine-5-carbonitriles by reactions of 2-cyano-3-ferrocenylacrylonitrile with amidines in aqueous medium is described. New fused 6-amino-2-ethoxy-4-ferroceny1-5-ferrocenylmethyl-5-ferrocenyl methyl-4,5dihydropyridine-3,5-dicarbonitrile was prepared in a tricomponent cyclodimerization from 2-cyano-3-ferrocenylacrylonitrile in presence of ethanol. The structures of the obtained compounds were established by IR, H-1 and C-13 NMR spectroscopy, mass-spectrometry and X-ray diffraction analysis. |
