describe an efficient for the synthesis of compounds of tautomeric β-pyridyl/quinolyl-enol, -ketone, -enaminone, which were finally characterized by standard methods like NMR, IR or SCXRD. The additionreaction of lithiated intermediates of picoline, 2-ethylpyridine and 2-methylquinoline, respectively, with nitriles followed by acid hydrolysis afforded the corresponding tautomeric compounds of enol,

In this work, various quinoline derivatives were prepared efficiently through a one-pot, three component synthesis using choline chloride/tin(II) chloride (ChCl·2SnCl2) deep eutectic solvent (DES) as a green catalyst. The procedure is free of using toxic solvents or catalyst and it could be categorized as a green method. In this procedure, aniline derivatives, aromatic aldehydes and enolizable aldehydes
