N-sulfonic acid pyridinium-4-carboxylic acid chloride as a novel and efficient catalyst for the condensation reaction of aldehyde with thiobarbituric acid and ammonium acetate
N-sulfonic acid pyridinium -4-carboxylic acid chloride {[Pyridine-N-SO3H-4-COOH]Cl} was synthesized, identified and applied as an effective catalyst for the preparation of pyrido[2,3-d:6,5-d]dipyrimidines by the condensation reaction of various aldehyde with 2-thiobarbituric acid and ammonium acetate under solvent-free conditions.The structure ofcatalyst was studied...
متن کاملAn Efficient Green Approach for the Synthesis of Fluoroquinolones Using Nano Zirconia Sulfuric Acid as Highly Efficient Recyclable Catalyst in two Forms of Water
Various antibacterial fluoroquinolone compounds were prepared by the direct amination of 7-halo-6- fluoroquinolone-3-carboxylic acids with a variety of piperazine derivatives and (4aR,7aR)-octahydro-1H-pyrrolo[3,4-b] pyridine using Zirconia Sulfuric Acid (ZrSA) nanoparticle, as a catalyst in the presence of ordinary or magnetized water upon reflux condition. The results showed that ZrSA exh...
متن کاملGreen Multicomponent Synthesis of Benzodiazepines in the Presence of CuFe2O4 as an Efficient Magnetically Recyclable Nanocatalyst under Solvent-Free Ball-Milling Conditions at Room Temperature
In this work, an efficient and green procedure for the synthesis of various substituted 1,5-benzodiazepine derivatives via a one-pot three-component catalytic reaction has been described. The reaction was conducted between o-phenylenediamine, dimedone and aldehyde derivatives in the presence of CuFe2O4 nanoparticles as a magnetic heterogeneous nanocatalyst under ball-milling conditions at room ...
متن کاملMelamine trisulfonic acid: An efficient and recyclable solid acid catalyst for the green synthesis of Biscoumarin derivatives
A novel catalytic synthesis of 3,3'-(arylmethylene)-bis-(4-hydroxy-2H-chromene-2-one) derivatives from a tandem condensation reaction of 4-hydroxycoumarin and aromatic aldehydes has been developed. The reaction occurs in water in the presence of Melamine trisulfonic acid as catalyst to give the corresponding products in good to high yields. This green approach has several advantages such as sho...
