An efficient and simple method has been reported for the synthesis of 2,3,4‐trisubstitutedquinolinesthrough zwitterion intermediate under reflux condition in presence of sulfuric acid. The formed dicarboxylate subsequently undergoes transesterification in various alcohols with good yields. Most of the synthesized compounds are newly reported characterized by spectroscopic method.

A series of 2,3,4‐trisubstitutedquinoline derivatives have been synthesized by reactions between 2‐aminoaryl ketones and dialkyl acetylenedicarboxylate. The synthetic pathway allows for the direct construction of said quinoline derivatives in pyridine/ethanol at ambient temperature through a zwitterion intermediate. J. Heterocyclic Chem., (2011)
A mild and efficient protocol for synthesis of quinoline derivatives in aqueousmedium under neutral conditions is described. The reaction proceeded smoothly in H2O catalyzed by supramolecular catalyst β‐CD. By this protocol, various quinoline derivatives were synthesized in excellent yields.

intramolecular annulation of β-enamino esters is described under solvent-free, calcium-catalysis. 2-aminoaryl ketones and alkylpropiolates undergone a [4+2] annulation to yield substituted quinolines; with an excess of alkylpropiolates, benzodiazepines were formed via a [4+2+1] annulation. We also described a one-pot, 3-component synthesis of quinoline derivatives via a [4+2+2] annulation. Interestingly
