A variety of 2,2,4 substituted 1,2-dihydroquinolines were synthesized from substituted anilines or aminoheterocycles and the corresponding ketones in good yield via the use of lanthanide catalysts and microwave technology. This method can be readily applied to the general synthesis of combinatorial libraries of dihydroquinolines.
An efficient process has been developed for the synthesis of 2,2,4-trisubstituted-1,2-dihydroquinolines in good yields through a simple one-pot condensation between anilines and ketones in the presence of zinctriflate as a catalyst at room temperature undersolvent-freeconditions.

Ceric ammonium nitrate (CAN) catalyzed the one-pot synthesis of 2,2,4-trimethyl-1,2-dihydroquinoline derivatives from substituted anilines and acetone via a modified Skraup reaction. The methodology was used to synthesize a novel dihydroquinoline-based compound derived from an anti-inflammatory agent nimesulide.

method using diaryl ditelluride. Further, monotellurides were converted into corresponding tellurium cations. Next, these Lewis acidic tellurium cations were used as catalysts to synthesize 1,2-dihydroquinolines from anilines and highly regioselective creation of β-aminoalcohols from epoxides.
