Condensation of 5-arylidene-2,2-dimethyl-1,3-dioxane-4,6-diones with 5,5-dimethyl-3-arylamino-2-cyclohexanones yields 1,4-diaryl-7,7-dimethyl-1,2,3,4,5,6,7,8-octahydroquinoline-2,5-diones.The compounds have been characterized from their IR, UV, and PMR spectra.It has been established that the N-phenyl ring, which projects from the plane of the octahydroquinolinedione ring, has a shielding effect on the magnetic field of the protons at the 7- and 8-positions of the ring in the molecules of the compounds synthesized.

N-Heterocyclic carbene (NHC)-catalyzed organocascade reactions via redox processes were found to be a simple and flexible procedure for the synthesis of a series of suitably functionalized 1-substituted 4-aryl-tetrahydroquinoline-2, 5-diones. A wide range of potential biologically active quinoline derivatives for biomedical screening were obtained.

Reactions of arylideneisopropylidenemalonates with 3-carboxyphenylaminocyclohexen-2-ones leads to N-carboxyphenyl-4-aryloctahydroquinoline-2,5-diones with elimination of acetone and carbon dioxide.
