Abstract
An effective protocol for synthesis of some new pyrazolylbarbiturate derivatives is reported through a one-pot, three-component reaction between barbituric/thiobarbituric acid, aroylphenylhydrazones and arylglyoxal derivatives. All reactions were conducted in ethanol as solvent without using any catalyst and products were obtained by simple filtering of the precipitated solids in high yields. All products were characterized by 1H and 13C NMR and IR spectral and elemental analysis data.
期刊介绍：
Synthetic Communications presents communications describing new methods, reagents, and other synthetic work pertaining to organic chemistry with sufficient experimental detail to permit reported reactions to be repeated by a chemist reasonably skilled in the art. In addition, the Journal features short, focused review articles discussing topics within its remit of synthetic organic chemistry.
