It was found that arylidenebisureas react with dimedone in acetic acid with the simultaneous formation of 9-aryltetramethyldecahydroacridine-1,8-diones and 9-aryltetramethyloctahydroacridine-1,8-diones in a ratio of 1:2.In the reaction of benzylidenebisurea with dimedone in formic acid 3,3,6,6-tetramethyl-1,2,3,4,5,6,7,8,9,10-decahydroacridine-1,8-dione s formed in addition to the hydrogenated 9-phenyltetramethylacridine-1,8-diones.
