Condensation of 2-naphthylamine or N-benzyl-2-naphthylamines with formaldehyde and methyl 2,2-dimethyl-4,6-dioxocyclohexane-3-carboxylate
摘要:
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.

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 beta-diketones of cyclohexanedione series.

A novel, atom economic, and environmentally friendly method for the synthesis of 2-substituted benzothiazoles and 2-substituted naphtho[2,1-d]yhiazoles from N-substituted arylamines and elemental sulfur has been developed under metal-free conditions. The reaction underwent the process of double C-Sbonds formation through C-H bonds functionalization.
