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

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.

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 ...

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.

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-
