CHARACTERISTICS OF HETEROCYCLIZATION OF TRIKETONES OF THE 2-(3-OXOPROPYL)CYCLOHEXANE-1,3-DIONE SERIES WITH HYDROXYLAMINE HYDROCHLORIDE

A rearrangement that leads to the formation of mixtures of 2,4- and 2,3-diarylsubstituted 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 recy
