The high potential of quinoline containing natural products and their derivatives in medicinal chemistry led us to discover novel series of 25 compounds for the development of new antileishmanial agents. A series of triazolyl 2-methyl-4-phenylquinoline-3-carboxylate derivatives has been synthesized via click chemistry inspired molecular hybridization approach and evaluated against Leishmania donovani. Most of the screened derivatives exhibited significant in vitro anti-leishmanial activity against promastigote (IC50 ranging from 2.43 to 45.75 μM) and intracellular amastigotes (IC50 ranging from 7.06 to 34.9 μM) than the control, miltefosine (IC50 = 8.4 μM), with less cytotoxicity in comparison to the standard drugs. Overall results revealed that prototype signify a new structural lead for antileishmanial chemotherapy.

The discovery of a new, malic acid promoted, eco-friendly Friedl?nder approach to varied multisubstituted quinolines is disclosed. To the best of our knowledge, this is the first report on the use of malic acid, classified as one of the 12 biobased hot molecules by the US Department of Energy, as an organopromoter in organic synthesis and includes many benefits like wide substrate scope, solvent free ambient reaction conditions, short reaction times, operational simplicity, cost effectiveness, high atom economy, good to excellent yields, and recylability of the organopromoter, making it a valuable green alternative to the existing methods. The versatility and practicability of the developed method was further established by its successful application towards the targeted synthesis of some important quinoline molecules and successful scale up.

- Versatile Barium and Calcium Imidazolium-Dicarboxylate Heterogeneous Catalysts in Quinoline Synthesis
-
This article details the development of heterogeneous catalysts based on calcium and barium in combination with the organic linker 1,3-bis(carboxymethyl)imidazolium (bcmim). The linker and the materials from alkaline earth metals are easily prepared under very smooth conditions. The use of linkers with different counterions (Cl or Br) provided different materials. Calcium- and barium-based catalysts were successfully employed in the preparation of quinoline derivatives from ketones and 2-aminoarylaldehydes or 2-aminoarylketones. In general, barium-based catalysts provided better results than calcium, although the latter are an excellent complement for certain substrates. Thus, a notable feature of such catalysts is the possibility of accessing a variety of complementary heterogeneous catalytic systems, rendering the catalysis adaptive to the reactant.||||||.

We report herein a series of acidic activated carbon materials, which can be considered as an environmentally friendly, cheaper alternative to the traditional acidic mesoporous silicates or even zeolites for the synthesis of quinolines/quinolones. Textural parameters of the acidic activated carbon materials together with their acidic properties are important factors that affect the reaction selectivity. Some mechanistic details have been addressed by computational calculations. Freeloading on the Friedlaender: Acidic microporous activated carbon materials containing sulfonic acid groups can be considered environmentally friendly and cheaper catalytic alternatives for the Friedlaender reaction compared to traditional acidic solids such as zeolites or even mesoporous silicates. The textural characteristics of the most efficient materials determine the parameters for the conversion and selectivity of the reaction. Copyright
