4a-Hydroxy-5-arylidene-9-methyl(phenyl)-1,2,3,4,4a,5,6,7,8,9a-decahydroxanthenes were obtained by the condensation of methyl(phenyl)bis(2-oxocyclohexyl)methanes and 2-hydroxy-8-methyl(phenyl)tricyclo2,7>tridecan-13-ones with benzaldehyde and anisaldehyde.When the products were boiled in acetic acid, the corresponding 4-arylidene-9-methyl(phenyl)-1,2,3,4,5,6,7,8-octahydroxanthenes were formed.In a mixture with acetic anhydride and acetic and 70percent perchloric acids the deca- and octahydroxanthenes are converted into 4-arylidene-9-methyl(phenyl)-1,2,3,4,5,6,7,8-octahydroxanthylium perchlorates, which in reaction with aromatic aldehydes gives 4,5-diarylidene-9-methyl(phenyl)-1,2,3,4,5,6,7,8-octahydroxanthylium perchlorates.When heated with ammonium acetate in acetic acid, the decahydroxanthenes are converted into 4-arylidene-9-methyl(phenyl)-1,2,3,4,5,6,7,8-octahydroacridines.
