Et 4,4-ethylenedioxocyclohexanone-2-carboxylate in its enolate form was subjected to react with acrylonitrile, acrylamide and 2-bromoacryloamide, and 4,4-ethylenedioxocyclohexanone in its enamine form with acrylamide, 4,4-ethylenedioxo-cyclohexanone-2-carbaldehyde in its keto-enamine form with cyanoacetamide and meldrum acid. Thus, ten new compounds, of which one hexa-hydro-2(1H)-quinolinone, three tetra- and hexa-hydro-2(1H)-quinolinone carboxylic acids and derivatives, three 9-oxa-bicyclo-[4.3.0]-1-nonenes, two 5-aminotetralins, and one cyanoethylated compound, were obtained. At the same time, the formation mechanisms of the bicyclo compounds and 5-aminotetralins were proposed, and a new synthetic method of 5-aminotetraline analogs was established. E.g., reaction of enamine I with meldrum acid and piperidine gave 35% 5-morpholinotetralin II.
