4-Aryl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxylates were synthesized by the reaction of aromatic aldehydes, 5,5-dimethyl-1,3-cyclohexanedione or 1,3-cyclohexanedione and 2-aminocroto- nate in ionic liquid [bmimBF4]. Compared with the previous methods, this new method has the advantages of high yields and environmental benignity. The structure of products was characterized by IR, 1H NMR spectra and elemental analyses, and further confirmed by X-ray analysis.
