Synthesis of two quinolines from one substrate: The beginning of regulating the duality of free radicals [PDF]

, 2022
Poly-substituted quinolines are scaffolds with diverse applications as pharmaceuticals, agrochemicals, electroluminescent materials, and dyestuffs. Herein, we present an effective scheme for the green synthesis of two multiply substituted quinoline ...

Transition-metal-free approach to quinolines via direct oxidative cyclocondensation reaction of N,N-dimethyl enaminones with o-aminobenzyl alcohols

Frontiers in Chemistry, 2022
A transition-metal-free method for the construction of 3-substituted or 3,4-disubstituted quinolines from readily available N,N-dimethyl enaminones and o-aminobenzyl alcohols is reported.

Multi-Substituted Quinolines as HIV-1 Integrase Allosteric Inhibitors

Viruses, 2022
Allosteric HIV-1 integrase (IN) inhibitors, or ALLINIs, are a new class of antiviral agents that bind at the dimer interface of the IN, away from the enzymatic catalytic site and block viral replication by triggering an aberrant multimerization of the ...

Quinoline Functionalized Schiff Base Silver (I) Complexes: Interactions with Biomolecules and In Vitro Cytotoxicity, Antioxidant and Antimicrobial Activities

Molecules, 2021
A series of fifteen silver (I) quinoline complexes Q1–Q15 have been synthesized and studied for their biological activities. Q1–Q15 were synthesized from the reactions of quinolinyl Schiff base derivatives L1–L5 (obtained by condensing 2 ...

Iron-catalyzed indolo[2,3-c]quinoline synthesis from nitroarenes and benzylic alcohols/aldehydes promoted by elemental sulfur

Green Synthesis and Catalysis, 2022
An iron-catalyzed strategy for the rapid synthesis of indolo[2,3-c]quinolines has been developed. This cascade reaction involving alcohol oxidation, nitro reduction, and oxidative annulation was achieved in a one-pot.

A Convenient One-Pot Preparation of 2-Methyl-3-(phenylthio- methyl)quinolines from Morita-Baylis-Hillman Adducts and Their Oxidation to the Corresponding Sulfones

Molecules, 2012
A convenient one-pot preparation of 2-methyl-3-(phenylthiomethyl)quinolines from Morita-Baylis-Hillman adducts via conjugate addition of thiols followed by reductive cyclization with Fe/AcOH was developed. The 2-methyl-3-(phenylthiomethyl)quinolines were

Controlled partial transfer hydrogenation of quinolines by cobalt-amido cooperative catalysis

Nature Communications, 2020
Controlling the partial reduction of quinolines is challenging, given the competing overreduction to tetrahydroquinolines. Here, the authors report a cobalt-amido cooperative catalyst for the selective, partial transfer hydrogenation of quinolines to 1,2-

TMSBr-Promoted Cascade Cyclization of ortho-Propynol Phenyl Azides for the Synthesis of 4-Bromo Quinolines and Its Applications

Molecules, 2019
Difficult-to-access 4-bromo quinolines are constructed directly from easily prepared ortho-propynol phenyl azides using TMSBr as acid-promoter. The cascade transformation performs smoothly to generate desired products in moderate to excellent yields with
