Arylglyoxal Monohydrates

A simple, clean, straightforward, and environmentally benign one-pot, three-component reaction of various arylglyoxal monohydrates, β-naphthol, and barbituric acid [pyrimidine-2,4,6(1H,3H,5H)-trione] or thiobarbituric acid in the presence of catalytic amounts potassium phthalimide-N-oxyl (PPINO), as a mild and efficient organocatalyst in aqueous media under reflux conditions is reported. This transformation produced the novel diverse-substituted 12-benzoyl-8,12-dihydro-9H-benzo[5,6]chromeno[2,3-d]pyrimidine-9,11(10H)-diones and their sulfur analogues in 82–93% yield via filtration and without utilization of any chromatography. The high yields of products, very simple operation, easy workup, availability of starting materials, green process, and high atom-economy are the main benefits of this synthetic strategy.

Simple Operation

Novel SO3H-functionalized ionic liquids were successfully applied as catalysts for synthesis of xanthenediones under microwave irradiation in Aqueous. Various types of Xanthenes were provided in 90-97% yields using the catalytic system of [(HSO3-p)2im][CF3SO3]/H2O. The products could be conveniently separated from the reaction mixture by filtration and the dissolved catalyst could be reused without any treatment, which of the separation process was performed in water without using any organic solvents. The method not only has the adventages of shrot time and simple operation, but also is environmentally friendly.

AbstractA green, efficient and simple protocol was developed for the synthesis of dihydropyrimido[4,5-d]pyrimidinetrione derivatives via a coupling reaction of 6-aminouracils, aromatic aldehydes and urea in aqueous media in the presence of nano-crystalline CuI at room temperature. The products were obtained in high yields. CuI nanoparticles can be recycled three times without significant loss of catalytic activity.
