Conclusions 1.Methods for synthesizing 4-methyl-6-phenyl-3-cyanopyridine-2[1H]thione were developed, based on the reaction of enamines with cyanothioacetamide, and 4-methyl-6-phenyl-3 -cyanopyridine-2[1H]selenone, based on the reaction of enamines or benzoylacetone with cyanoselenoacetamide.2.The reaction of benzoylacetone with cyanothioacetamide leads to the formation of a mixture of 4-methyl-6-phenyl- and 6-methyl-4-phenyl-3-cyanopyridine-2[1H]thiones in a ratio of 2:1.3.Alkylation of 3-cyanopyridine-2[1H]thiones and 3-cyanopyridine-2[1H]selenones, proceeding through the intermediate formation of 3-cyano-2-alkylthio(seleno)pyridines, leads to derivatives of 3-aminothieno-[2,3-b]- and 3-aminoselenopheno[2,3-b]pyridines. |
