Condensation of 2-naphthylamine with formaldehyde and methyl 2,2-dimethyl-4,6-dioxocyclohexanecarboxylate afforded depending on the reaction conditions methyl 9,9-dimethyl-11-oxo-8,9,10,12-tetrahydro-7H-benzo[a]acridine-10-carboxylate or 4-alkoxymethyl-1,4-dihydro-2',6'-dioxo-4',4'-dimethyl-2'H,3H,6'Hspirobenzo[f]quinoline-2,1'-cyclohexyl-3'-carboxylate. The condensation of N-benzyl-2-naphthylamines with formaldehyde and methyl 2,2-dimethyl-4,6-dioxocyclohexanecarboxylate provided with the quantitative yield the corresponding methyl 4-benzyl-1,4-dihydro-2',6'-dioxo-4',4'-dimethyl-2'H,3H,6'H-spirobenzo[f]quinoline-2,1'-cyclohexyl-3'-carboxylates.
