Efficient Conversion of Carbohydrates to 5-Hydroxymethylfurfural (HMF) Using ZrCl4 Catalyst in Nitromethane

Application of ZrO2–SO3H as highly efficient recyclable nano-catalyst for the green synthesis of fluoroquinolones as potential antibacterial

Various antibacterial fluoroquinolone compounds were prepared by the direct amination of 7-halo-6- fluoroquinolone-3-carboxylic acids with variety of piperazine derivatives and (4aR,7aR)-octahydro-1H-pyrrolo[3,4-b] pyridine using Zirconia Sulfuric Acid (ZrSA) nanoparticle, as a catalyst in refluxing water. The results showed that ZrSA exhibited high catalytic activity towards the synthesis of f...

Montmorillonite KSF as a very efficient heterogeneous catalyst for the synthesis of 5-substituted 1H-tetrazoles

Montmorillonite KSF has been used as an effective and non-toxic heterogeneous catalyst for one-pot synthesis of 5-substituted 1H-tetrazoles via [3+2] cycloaddition of sodium azide with a wide variety of nitriles. The reaction afforded high yields of the desired products in a short reaction time under mild reaction conditions. The catalyst can be recovered by simple filtration and reuse...

SbCl3 as an Efficient Catalyst for the One-pot Synthesis of Highly Substituted Piperidines

Highly substituted piperidines were synthesized via the condensation of aromatic aldehydes and aromatic amines with β-ketoesters in the presence of antimony(III) chloride at ambient condition. This reaction has any advantages such as easy work-up, clean procedure, and good yields.
