Manganese-Catalyzed Asymmetric Hydrogenation of Quinolines Enabled by pi–pi Interaction [PDF]

, 2020
The first example of non-noble metal-catalyzed asymmetric hydrogenation of aromatic N-heterocycles is reported. A new chiral pincer manganese catalyst showed outstanding catalytic activity in the asymmetric hydrogenation of a wide range of quinolines ...

Application of Heteropoly Acids as Heterogeneous and Recyclable Catalysts for Friedländer Synthesis of Quinolines

E-Journal of Chemistry, 2010
New convenient conditions for the Friedländer synthesis of quinolines are described. Quinolines were readily prepared in the presence of heteropolyacids as heterogeneous and recyclable catalysts in good yields.

Therapeutic Activity of a Topical Formulation Containing 8-Hydroxyquinoline for Cutaneous Leishmaniasis

Pharmaceutics, 2023
Cutaneous leishmaniasis exhibits a wide spectrum of clinical manifestations; however, only a limited number of drugs are available and include Glucantime® and amphotericin B, which induce unacceptable side effects in patients, limiting their use.

Multicomponent Synthesis of 4-Aryl-4,9-dihydro-1H-pyrazolo[3,4-b]quinolines Using L-Proline as a Catalyst—Does It Really Proceed?

Molecules, 2023
Looking for effective synthetic methods for 1H-pyrazolo[3,4-b]quinolines preparation, we came across a procedure where, in a three-component reaction catalysed by L-proline, 4-aryl-4,9-dihydro-1H-pyrazolo[3,4-b]quinolines are formed.

Synthesis of Azuleno[2,1-b]quinolones and Quinolines via Brønsted Acid-Catalyzed Cyclization of 2-Arylaminoazulenes

Molecules, 2023
Quinolone and quinoline derivatives are frequently found as substructures in pharmaceutically active compounds. In this paper, we describe a procedure for the synthesis of azuleno[2,1-b]quinolones and quinolines from 2-arylaminoazulene derivatives, which

Efficient synthesis and antioxidation activities of ferrocenylpyrano-fused quinolines

四川大学学报. 自然科学版, 2022
Fifteen known ferrocenylpyrano-fused quinolines were synthesized efficiently via three-component Povarov reaction of 4-methyl-7-aminobenzopyranone, aromatic aldehydes, and ferrocenyl acetylene in the presence of cerium trifluoromethylsulfonate (Ce(OTf)3)

N-(Quinolin-8-yl)quinoline-2-carboxamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2012
In the title compound, C19H13N3O, the dihedral angle between the two quinoline systems is 11.54 (3)°. The molecular conformation is stabilized by intramolecular N—H...N and C—H...O hydrogen bonds, with N—H...N being bifurcated towards the two N atoms of the two quinoline rings.
