one-pot synthesis of polysubstitutedquinoline derivatives has been demonstrated by using sulfamic acid as a reusablecatalystundersolvent-freeconditions. The synthetic method provides the basis and advantages of a simple experimental procedure and easy recovery and reuse of catalyst, which makes it a highly practical and environmentally benign pathway for the synthesis of polysubstituted quinolines
An efficient method for the direct synthesis of substituted quinolines from anilines and aldehydes through C–H functionalization, C–C/C–N bond formation, and C–C bond cleavage has been developed. The method is simple and practical and employs air as an oxidant.

A variety of diallylanilines are shown to undergo cobalt-carbonyl catalyzed rearrangement to quinolines. Diallylanilines are also used as allyl transfer reagents to convert benzaldimines into quinolines. Substitution in the 2- and 3-positions of the quinoline is featured in all transformations.

Sulfonic acid functionalized ionic liquid (FIL-A) was firstly used as a recoverable and reusable catalyst for the synthesis of 2-alkylquinoline derivatives from simple and readily available alkylaldehydes and arylamines. The method has the advantages of simple experimental procedure, easy recovery and reuse of catalyst, solvent-free and mild reaction conditions, excellent functional group tolerance, etc. which makes it a highly practical and environmentally benign pathway for the synthesis of 2-alkylquinolines.
