Condensation of N-monosubstituted 2-naphthylamines, formaldehyde, and cyclic β-diketones. One-pot synthesis of 2,4-disubstituted derivatives of 1,2,3,4-tetrahydrobenzo[f]quinoline

Various spirocyclic derivatives of 1,2,3,4-tetrahydrobenzo[f]quinoline containing substituents in the positions 2 and 4 of the ring were obtained by one-pot multicomponent condensation of available N-benzyl-2-naphthylamines, formaldehyde, and cyclic β-dik

Synthesis of ethyl 2-hydroxy-3-[aryl(2-naphthylamino)methyl]-2-cyclopentenecarboxylates and ethyl 3-arylmethylene-2-(2-naphthylamino)-1-cyclopentenecarboxylates

Condensation of N-arylmethylene-2-naphthylamines with ethyl 2-oxocycopentanecarboxylate in the presence of HCl or CH3COOH yields ethyl 2-hydroxy-3-[aryl(2-naphthylamino)methyl]-2-cyclopentene-carboxylates and ethyl 3-arylmethylene-2-(2-naphthyl

Synthesis of benzo[a]phenanthridine derivatives by condensation of N-arylmethylene-2-naphthylamines with 5-phenyl- and 5-(p-methoxyphenyl)-1,3-cyclohexanediones

Condensation of N-arylmethylene-2-naphthylamines with 5-phenyl- and 5-(p-methoxyphenyl)-1,3-cyclohexanediones in various solvents gave new hexahydrobenzo[a]phenanthridin-4-one derivatives. Three-component condensation of 2-naphthylamine, appropriate aldeh

Synthesis of 5-aryl-1,2,3,4-tetrahydrobenzo[a]phenanthridines

Previously unknown derivatives of tetrahydro[a]phenanthridine containing annelated benzoquinoline and cyclohexene nuclei were prepared by condensation of azomethines of the 2-naphthylamine series with cyclohexanone. The possibility of synthesis of such compounds without preliminarily preparing Schiff bases was demonstrated. The effect of substituents in the aromatic ring of the azomethine on the yield of the target products was elucidated. The IR, UV, 1H NMR, and mass spectra of the synthesized compounds were discussed.
