A convenient one-potsynthesis of 2,3-disubstituted, 2,3,6-trisubstituted, and 2,3,6,7-tetrasubstituted quinoline analoguesfrom terminal alkynes via sequential ruthenium(II) and para-toluenesulfonic acid (p-TSA) co-catalyzed reactions is described. The catalytic process is shown to take place first via intermediate formation of an allyl ketone and then addition of an aniline derivative to the allyl

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

A novel and an expedient metal- and solvent-free synthesis of a wide variety of 2-benzyl-4-arylquinoline derivatives is described from readily available arylamines, styrene oxides and aryl acetylenes in the presence of 10 mol% molecular iodine. This domino reaction occurs under metal- and solvent-free conditions at 120 °C, which avoids the usage of metal catalyst and as a consequence generation of
A new catalytic amination of aromatic olefins with anilines is presented. In a domino reaction, substituted quinoline derivatives are obtained in the presence of cationic rhodium complexes, such as [Rh(cod)2]BF4, and PPh3. Ethylbenzene is formed as a by-product in this new oxidative reaction. The first transition metal catalyzed anti-Markovnikov hydroamination of styrene with anilines occurs as a side

efficient and straightforward method for the synthesis of 2-benzyl-3-arylquinoline derivatives is reported involving the domino reaction of substituted arylamines and styrene oxides in the presence of 10 mol% ytterbium(III) triflate in acetonitrile at 80 °C. Additionally, the reaction of aliphatic epoxides with p-anisidine provided 2,3-dialkylquinoline derivatives under identical reaction conditions. Important
