An Efficient Microwave Assisted Eco-friendly Synthesis of 6-Chloro-3-(3-arylacryloyl)-2-methyl-4-phenylquinolines and their Conversion to 6-Chloro-3-(1-phenyl-5-aryl-4,5-dihydro-1H-pyrazol-3-yl)-2-methyl-4-phenylquinolines

An eco-friendly basic alumina catalyzed protocol for the synthesis of some new quinolinyl chalcones has been developed by microwave assisted methods which in turn are converted to pyrazoline derivatives.
