Shelyakin V. Cyclization reactions of the functionally sub-stituted 1,3-dicarbonyl compounds heterocyclic row with cyanoacetic acide derivatives

. The reactions of 1,3-dicarbonyl compounds of heterocyclic row were investigated for the first time considering steric position of 1,3-dicarbonyl function and cyanoacetic acid derivatives in them. Convenient methods of the functionally substituted oxygen-, nitrogen-, silfur-containing heterocyclic compounds synthesis were elabo-rated at reactions of 1,3-dicarbonyl heterocyclic row compounds. New stable heterocyclic row sulfides were synthesized, including those which contain electron-acceptor substituents in their structure, 3-aminothiophenes were obtained ay their base including those which are annelated with isoquinoline, cyclopenta[c]pyridine, 1,6-naphtiridine, 5-alkyl-6-(2-thienyl)-pyridine cycles.
