A series of methyl 5-oxo-4-aryl-1,4,5,6,7,8-hexahydroquinolin-3-carboxylates were synthesized by the reaction of aromatic aldehydes, methyl β-aminocrotonate and 5,5-dimethyl-1,3-cyclohexanedione (or 1,3-cyclohexanedione) in the presence of triethylbenzylammonium chloride (TEBA) in aqueous media. Compared to the previous method, this new protocol has the advantages of high yields, inexpensive medium and environmental friendliness.

Key words: synthesis, green chemistry, hexahydroquinoline, aqueous media
