Click chemistry-inspired design, synthesis, and molecular docking studies of biscoumarin derivatives using carbon-based acid catalyst

A green and eco-benign synthesis of biscoumarin derivatives using carbon sulfonic acid, a solid support catalyst has been described. The reaction involved a one-pot two-component reaction of 4-hydroxycoumarin and aldehyde using carbon sulfonic acid involv

Efficient synthesis of bis-(4-hydroxycoumarin) using sulfanilic acid as recyclable catalyst in water

A catalytic reaction between aromatic aldehydes and 4- hydroxycoumarin has been developed to form a decent range of functionalized biscoumarin skeletons in excellent yields using sulfanilic acid as reusable catalyst in aqueous media. The catalytic reactio

Green synthesis of bis-coumarin derivatives using Fe(SD)3 as a catalyst and investigation of their biological activities

A convenient, practical, green, and environmentally friendly method was developed for the synthesis of biscoumarins and corresponding tetrakis products from the reaction of 4-hydroxycoumarin and various aldehydes. The bis-coumarins were synthesized in hig

Investigation of catalytic, anti-bacterial, anti-oxidant, and DNA cleavage properties of bimetallic and trimetallic magnetic nanoalloys base on cupper

Bimetallic and trimetallic magnetic nanoalloys base on cupper were easily prepared from their starting materials. These nanoparticles (NPs) were used for the synthesis of biscoumarines by two-component one-pot domino Knoevenagel-type condensation/Michael

Efficient synthesis of bis(indolyl)methanes, bispyrazoles and biscoumarins using 4-sulfophthalic acid

Zwitterionic liquid (ZIL) coated CuO as an efficient catalyst for the green synthesis of bis-coumarin derivatives: via one-pot multi-component reactions using mechanochemistry

A convenient, solvent free strategy for the synthesis of bis-coumarins has been developed using zwitterionic liquid (ZIL) coated copper oxide (CuO) and mechanical ball milling. The ZIL were fabricated from imidazolium/benzimidazolium and sulfonate/carboxy

Grinding technique for the tandem synthesis of BIS coumarinyl methanes using [BDBDMIm]Br-CAN

3,3-(Butane-1,4-diyl)bis(1,2-dimethyl-1H-imidazole-3-ium)bromide ([BDBDMIm]Br) is easily used as an efficient and recyclable ionic liquid for the synthesis of bis coumarinyl methanes in the presence of a catalytic amount of ceric ammonium nitrate (CAN) under grinding. All reactions are performed in the absence of solvent in excellent yield during short reaction time. Furthermore, the ionic liquid can be reused and recovered for several times without loss of activity. This method provides several advantages such as simple work-up, environmental friendliness and shorter reaction time along with high yields. All of synthesized compounds were characterized by infrared spectroscopy,1H and13C nuclear magnetic resonance spectroscopy and elemental analyses.

Synthesis of bis coumarinyl methanes using Fe3O4@SiO2@KIT-6 as an efficient and reusable catalyst

Background: Coumarin constitutes one of the major classes of naturally occurring compounds. In the well-known family of coumarin derivatives, dimeric coumarins (also called biscoumarins) occupy an interesting position. Although some types of these compoun

L-Tyrosine loaded nanoparticles: An efficient catalyst for the synthesis of dicoumarols and Hantzsch 1,4-dihydropyridines

Environmentally benign l-tyrosine loaded nanoparticles are fabricated and characterized by PCS, TEM, FT-IR and AFM studies. A novel straightforward green approach was applied for the synthesis of dicoumarols and Hantzsch 1,4-dihydropyridines using this catalyst. The structures and purity of these compounds were confirmed by FT-IR and NMR (1H, 13C and DEPT). The flexible and swelling properties of the polymer coating increase l-tyrosine dispersion and its high catalytic activity in organic reactions. This journal is
