Clean procedure for synthesis of chromeno[4,3-b]benzo [f]quinolin-6-one derivatives: Reaction of N-arylidenenaphthalen-2-amine with 4-hydroxycoumarin in aqueous media
A short and simple synthesis of chromeno[4,3- b ]benzo[ f ]quinolin-6-one derivatives was accomplished in good to high yields via the reaction of N -arylidenenaphthalen-2-amine with 4-hydroxycoumarin in aqueous media catalyzed by TEBAC. The structures wer
A clean procedure for the synthesis of chromeno[4,3-b]benzo[f]quinoline and quinolino[4,3-b]benzo[f]quinoline derivatives in aqueous media
A short and simple synthesis of chromeno[4,3-b]benzo[f]-quinoline and quinolino[4,3-b]benzo[f]quinoline derivatives were accomplished in high yields via the reaction of N-benzilidenenaphthalen-2-amine and 4-hydroxycoumarin or 4-hydroxyquinolin-2-one in aq
Reaction of β-Arylidennaphthylamines with 4-Hydroxycoumarin. A Correction in Structural Assignment of the Product. III.
The reaction of 4-hydroxycoumarin with β-arylidennaphthylamines constitutes a convenient synthetic route to the hitherto unknown 2H-benzobenzopyranoquinolin-2-one, VI.The X-ray crystallography data conform with the present benzopyranoq
