Reaction of 2′-hydroxy[1,1′;3′,1″]terphenyl-5′-carbaldehyde with 2-naphthylamine and 1,3-diketones

The condensation of 2′-hydroxy[1,1′;3′,1″]terphenyl-5′-carbaldehyde with 2-naphthylamine and 1,3-cyclohexanedione or dimedone gave 7,8,9,10,11,12-hexahydrobenzo[a]acridin-11-ones, while analogous three-component condensation with 1,3-indandione afforded azaindeno[1,2-b]phenanthren-12-one. In addition, hexahydro-2H-xanthene-1,8-diones and arylmethylenebisdiketones were isolated as by-products.
