Synthesis and evaluation of biological activity of novel chromeno[4,3-b]quinolin-6-one derivatives by SO3H-tryptamine supported on Fe3O4@SiO2@CPS as recyclable and bioactive magnetic nanocatalyst
Abstract Newderivatives of chromeno[4,3-b]quinolin-6-one were synthesized using novel SO3H-tryptamine supported on Fe3O4@SiO2@CPS which could be recycled as an effective magnetic nanocatalyst. SEM, EDX, XRD, FT-IR, TGA, VSM and BET analyses were utilized to confirm the magnetic nanocatalyst structure. Evaluation of Antimicrobial (antibacterial and antifungal) function of magnetic nanocatalyst as well

An efficient synthesis of novelcoumarinderivativesvia a three‐component condensation of 4‐hydroxycoumarin, aldehydes and aromatic amines catalyzed by sulfonic acid functionalized ionic liquid L‐2‐(hydroxymethyl)‐1‐(4‐sulfobutyl)pyrrolidinium hydrogen sulfate ([HYSBPI]·HSO4) is reported. The condensed product was obtained with excellent yields in water under microwave irradiation condition. The antitumor
Synthesis and application of CoFe₂O₄@THAM@PHG‐SO₃H nanoparticles as a new and highly recyclable nanocatalyst in the one‐pot multicomponent synthesis of 3,4‐dihydropyranochromenes and chromeno[3,4‐<i>b</i>]quinoline‐6‐ones
catalytic efficiency of the nanocatalyst in two reactions: the synthesis of 3,4-dihydropyranochromenes from the reaction among aromaticaldehydes, 4-hydroxycoumarin, and malononitrile, and the synthesis of chromeno[3,4-b]quinoline-6-ones from the reaction among aniline, 4-hydroxycoumarin, and aromaticaldehydes.
