- OCTAHYDROPYRROLOACRIDINE DERIVATIVES. 2. 1-ARYL-4,4,8,8-TETRAMETHYL-2,3,4,5,7,8,9,10-OCTAHYDROPYRROLOACRIDIN-10-ONES AND INTERMEDIATES IN THEIR SYNTHESIS
-
A series of 9-aroyl-3,3,6,6-tetramethyl-1,2,3,4,5,6,7,8-octahydroxanthen-1,8-diones has been prepared from arylglyoxals and dimedone in a dehydrating medium; upon heating with ammonia these compounds are converted to 1-aryl-4,4,8,8-tetramethyl-2,3,4,5,7,8,9,10-octahydropyrroloacridin-10-ones.These reactions occur via the intermediate formation of tetrahydroindole derivatives.
