One-pot synthesis of hexahydroquinolines<i>Via</i>a four-component cyclocondensation under microwave irradiation in solvent free conditions: A green chemistry strategy
Four-componentcyclocondensation of aromatic aldehydes, malononitrile, dimedone and ammonium acetate proceeds undermicrowaveirradiation in solventfreeconditions to give highly functionalized hexahydroquinolines in excellent yields.

Abstract An efficient and swift microwave (MW)-mediated procedure for synthesis of 11 quinoline derivatives has been designed based on reaction between aromatic aldehydes, malononitrile, 5,5-dimethylcyclohexane-1,3-dione, and ammonium acetate at room temperature in ethanol solvent. The main advantages of this method are operational simplicity, excellent yield (92–98 %), use of green solvent, short
