Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Condensation products with azaphthalidylidene structures were obtained by the reaction of anhydrides of cinchomeronic and pyrazine-2,3-dicarboxylic acids with malonic ester, thiazolidine-2,4-dione, N-phenylthiazolidine-2,4-dione, and rhodanine. Azaindan-1,3-dione derivatives were synthesized with cyanoacetic ester and malononitrile under the same conditions. The reaction of these anhydrides, as well as quinolinic acid anhydride, with α- and γ-methylquinolines, as well as 2,6-lutidine, gave compounds that have azaphthalidylidene structures, which were converted to azaquino- and pyrophthalones by the action of sodium methoxide.
