- Photocatalytic Synthesis of Quinolines via Povarov Reaction under Oxidant-Free Conditions
-
We describe here an approach for synthesizing quinolines either from N-alkyl anilines or from anilines and aldehydes. A dual-catalyst system consisting of a photocatalyst and a proton reduction cocatalyst is employed. Without the use of any sacrificial ox

- One-Pot Oxidative Synthesis of Substituted Quinolines from Alcohols and Arylamines Catalyzed by Fe(CrO2)2 in Water Medium
-
One-pot tandem synthesis was developed for substituted quinolines (in up to 97% yields) involving a selective catalytic oxidation of primary amines to aldehydes and their condensation with arylamines under the action of a dispersion of Fe(CrO2)2 and water solution of H2O2 at room temperature. The stage of catalytic oxidation of alcohols was accelerated by photoactivation. A presumable mechanism of the photoactivated tandem synthesis of 2-methylquinoline was suggested. Catalyst Fe(CrO2)2 was prepared by photochemical synthesis.

- Fe(CrO2)2-catalyzed, photoactivated oxidative one-pot tandem synthesis of substituted quinolines from primary alcohols and arylamines
-
[Figure not available: see fulltext.] A one-pot tandem synthesis of substituted quinolines involving selective catalytic oxidation of primary alcohols to the corresponding aldehydes and their subsequent condensation with arylamines has been developed. Fe(CrO2)2 has been used as a catalyst, and oxidation has been performed with aqueous H2O2. To accelerate the catalytic oxidation of alcohols, photoactivation method has been applied.

- Quinoline Synthesis by the Reaction of Anilines with 1,2-diols Catalyzed by Iron Compounds
-
The synthesis of quinoline derivatives by cyclocondensation of anilines with 1,2-ethanediol, 1,2-propanediol, and 1,2-butanediol in the presence of iron-containing catalysts was performed for the first time.

- The Rhodium Complex-catalyzed Synthesis of Quinolines from Aminoarenes and Aliphatic Aldehydes
-
A variety of aminoarenes react with aliphatic aldehydes in the presence of a catalytic amount of a rhodium complex and an excess amount of the corresponding nitroarenes at 180 deg C to give 2-alkyl- and 2,3-dialkyl-substituted quinolines in excellent yields.Among the rhodium complexes examined, 2 exhibits the highest activity as a catalyst.Thus, 2-methyl-, 2-ethyl-3-methyl-, 2-propyl-3-ethyl-, 2-butyl-3-propylquinoline derivatives are readily obtained from aminoarenes and ethanal, propanal, butanal, and pentanal respectively.
