The 2,4-diarylquinolines (3) were obtained in a one-pot synthesis by photochemical and subsequent thermal reactions of 1,4,6-triarylpyrimidin-2(1H)-ones (1) in fair yield.The quinolines (3) were formed via thermal cycloreversion, followed by electrocyclic ring-closure, of the 1,3-diazabicyclohex-5-en-2-ones (2), which were produced by photochemical electrocyclization of the pyrimidin-2(1H)-ones (1).

2,4-Diphenylquinolines (3) were quantitatively prepared by heating of 3-aryl-4,6-diphenyl-2-oxo-1,3-diazabicyclohex-5-enes (2), which were obtained by photochemical electrocyclization of 1-aryl-4,6-diphenyl-2(1H)-pyrimidin-2-ones (1), in benzene at reflux temperature.
