A rearrangement that leads to the formation of mixtures of 2,4- and 2,3-diaryl-substituted 5-oxotetrahydroquinoline oximes was observed in the heterocyclization of oxo 1,5-diketones of the 2-(3-oxopropyl)cyclohexane-1,3-dione series, as well as in the recyclization of 5-oxotetrahydro-4H-chromenes, in the presence of excess hydroxylamine hydrochloride. It was established that the rearrangement proceeds only when electron-donor groups are present in the starting compounds. |
