Previously unknown 1-[2-aryl(quinolin-2-yl)ethenyl]-3-[aryl(quinolin-2-yl)]benzo[f]quinolines and 3-aryl-1-(2-arylethenyl)-4,7-phenanthrolines were synthesized by reactions of 1-methylbenzo[f]quinolines and 1-methyl-4,7-phenanthrolines with substituted N-benzylideneanilines and N-(quinolin-2-ylmethylidene)aniline on heating in dimethylformamide in the presence of potassium hydroxide.

A series of unexpected pyrimidine spiro-benzoquinolines were developed based on the reaction of N-(arylidene)naphthalen-2-amine, arylaldehyde, 1,3-dimethylbarbituric acid in aqueous media catalyzed by triethylbenzylammonium chloride (TEBAC). The structure of the product 4a was confirmed by X-ray diffraction studies. In addition, the water was chosen as green solvent.

Previously unknown derivatives of tetrahydro[a]phenanthridine containing annelated benzoquinoline and cyclohexene nuclei were prepared by condensation of azomethines of the 2-naphthylamine series with cyclohexanone. The possibility of synthesis of such compounds without preliminarily preparing Schiff bases was demonstrated. The effect of substituents in the aromatic ring of the azomethine on the yield of the target products was elucidated. The IR, UV, H-1 NMR, and mass spectra of the synthesized compounds were discussed.
