A One-Pot, Solvent-Free, and Catalyst-Free Synthesis of Substituted (E)-1-Phenyl-3-[2-(piperidin-1-yl)quinolin-3-yl]prop-2-en-1-ones Under Microwave Irradiation

详细

A convenient one-pot, three-component, and solvent-free procedure for the preparation of substituted (E)-1-phenyl-3-[2-(piperidin-1-yl)quinolin-3-yl]prop-2-en-1-ones, which has made a significant improvement of previously reported methods, has been developed. The reaction of chloro aldehydes, ketones, and piperidine under microwave irradiation afforded the corresponding piperidine-substituted chalcone derivatives in high yields in shorter reaction times. All the synthesized compounds were characterized by IR and ¹H and ¹³C NMR spectroscopy, and mass spectroscopy.
