A clean and simple synthesis procedure for benzo[f]quinolin-3-carbonyl urea and thiourea derivatives was developed based on the reaction between N-arylidenenaphthalen-2-amine and barbituric acid or thiobarbituric acid in aqueousmediacatalyzed by triethylbenzylammonium chloride (TEBAC). It was interesting that the structures of products in solvent of DMSO-d6 solution were different from those of the

Reaction of N-arylidenenaphthalen-2-amine and 4-hydroxy-6-methylpyran-2-one in aqueous media catalyzed by triethylbenzylammonium chloride (TEBAC) at 90 °C unexpectedly gave a pyrone ring-opening product 1-aryl-1,4-dihydro-3-[(E)-2-hydroxyprop-1-enyl]-N-(naphthalene-2-yl)benzo[f]quinoline-2-carboxamide. Modification of the reaction protocol resulted in a three-component reaction among N-arylidenenaphthalen-2-amine, 4-hydroxy-6-methylpyran-2-one and naphthalen-2-amine.

A series of unexpected pyrimidine spiro-benzoquinolines were developed based on the reaction of N-(arylidene)naphthalen-2-amine, arylaldehyde, 1,3-dimethylbarbituric acid in aqueous media catalyzed by triethylbenzylammonium chloride (TEBAC). The structure of the product 4a was confirmed by X-ray diffraction studies. In addition, the water was chosen as green solvent.
A Clean Procedure for the Synthesis of Chromeno[4,3-<i>b</i>]benzo[<i>f</i>]quinoline and Quinolino[4,3-<i>b</i>]benzo[<i>f</i>]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 aqueousmedia catalyzed by TEBAC. The structures were established by spectroscopic data and further confirmed by X-ray diffraction analysis.
