Nano-Fe3O4@ZrO2-SO3H as highly efficient recyclable catalyst for the green synthesis of fluoroquinolones in ordinary or magnetized water
Core–shell zirconia-coated magnetite nanoparticle bearing sulfonic acid groups (nano-Fe3O4@ZrO2-H3PO4) have been prepared and used as an efficient acid catalyst in the synthesis of fluoroquinolons by the direct amination of 7-halo-6- fluoroquinolone-3-carboxylic acids with variety of piperazine derivatives and (4aR,7aR)-octahydro-1H-pyrrolo...

متن کاملA green protocol for synthesis of pyran annulated hetrocyclic systems using Na2SO4 as an efficient catalyst
Na2SO4 as an inexpensive and effective catalyst has provided a green protocol for the synthesis of tetrahydrobenzo[b]pyran, pyrano[2,3-d]pyrimidinone and dihydropyrano[3,2c]chromene derivatives from the three-component domino reaction of aromatic aldehydes and malononitrile with 4-hydroxycoumarin/ dimedone/ barbituric acid in ethanol/water as a mixture of solvent that, this mixture entirely is ...
