Investigation of the products of interaction of cyclic diketones with nitrogen-containing 1,4-binucleophiles

The interaction of arylbis(5,5-dimethylcyclohexane-1,3-dion-2-yl)methanes with o-phenylenediamine and o-aminophenol leads to the preparation of 3,3-dimethyl-11-aryl-2,3,4,5,10,11-hexahydrobenzo[b,e]-1,4-diazepin-1-ones and 3,3,6,6-tetramethyl-9-aryl-10-(2-hydroxyphenyl)-2,4,5,7,9-decahydroacridine-1,8-diones respectively. A one-pot method is proposed for the synthesis of derivatives of hexahydrodibenzo[b,e]-1,4-diazepin-1-ones. The structure of the first member of this series was confirmed by X-ray diffraction analysis.
