A mild and efficient catalytic method for synthesis of 5-alkoxycarbonyl-4-aryl-3, 4dihydropyrimidin-2(1H)-ones using KSF montmorillonite as catalyst is described.
متن کاملMontmorillonite 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...
متن کاملAn efficient synthesis of 4-aryl-7-benzylidene-hexahydro-2H-cyclopenta[d] pyrimidin-2-ones/thiones catalyzed by p-dodecylbenzenesulfonic acid
A new and efficient method has been developed for the synthesis of 4-aryl-7-benzylidene-1,3,4,5,6,7-hexahydro-2H-cyclopenta[d]pyrimidin-2-ones through Biginelli-like reaction of cyclopentanone, with urea/thiourea and aromatic aldehyde employing p-dodecylbenzenesulfonic acid (DBSA) as a recyclable catalyst under solvent-free condition. The recovered catalyst was recycled for further runs. The pr...
