Oxidative aromatization of some 1,4-dihydropyridines by aqueous hydrogen peroxide in ethanol
Volume 3, Issue 2, pp. 72-147, Serial No. 7 , April 2015, , Pages 143-147
Abstract
Some 3, 5-diacyl or 3,5-diester 1,4-dihydropyridines were oxidized to the corresponding pyridine derivatives using hydrogen peroxide in aqueous ethanol in the presence of potassium bromide and acetic acid as the catalysts. The reaction was carried out in ethanol and products were isolated in high to ... Read More)
Ag nanoparticle/melamine sulfonic acid supported on silica gel as an efficient catalytic system for synthesis of dihydropyrimidin thiones
Volume 2, Issue 3, pp. 162-231, Serial No. 4 , July 2014, , Pages 180-186
Abstract
3,4-dihydropyrimidin-2(1H)-thiones were synthesized in the presence of Ag nanoparticle/melamine sulfonic acid (MSA) supported on silica gel. The reaction was carried out at 110 oC for 20 min under solvent free conditions. In all cases, the three component reaction proceeded smoothly to give the corresponding ... Read More)
