Substituted quinolines were effectively synthesised by utilising chlorotrimethylsilane (TMSCl) as an efficient catalyst in the cyclisation condensation of aromatic amines and enolisable aldehydes via a tandem process in air and DMSO. The clean, mild reaction conditions, operational simplicity and high yields were attractive features of the reaction which enables a facile preparative procedure for building

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.
