OCTAHYDROPYRROLOACRIDINE DERIVATIVES. I. SYNTHESIS AND MOLECULAR STRUCTURE OF DERIVATIVES OF 2,3,4,5,7,8,9,10-octahydropyrroloACRIDIN-10-ONE, A NEW HETEROCYCLIC SYSTEM

Heating 1,1-bis(5,5-dimethyl-1,3-cyclohexadienon-2-yl)acetone with ammonia gave a new heterocyclic compound, namely, 1,4,4,8,8-pentamethyl-2,3,4,5,7,8,9,10-octahydropyrrolo<4,3,2-m,n>acridin-10-one.Analogously, 3,6-dimethyl-9-benzoyl-1,2,3,4,5,6,7,8-octahydroxanthene-1,8-dione gave 4,8-dimethyl-1-phenyl-2,3,4,5,7,8,9,10-octahydropyrrolo<4,3,2-m,n>acridin-10-one.The structures of these products were demonstrated by PMR and IR spectroscopy and x-ray diffraction analysis.
