Synthesis of new derivatives of pyrazol-chromeno[2,3-d]pyrimidine-ones by a one-pot three-component reaction

Synthesis of new derivatives of pyrazol-chromeno[2,3-d]pyrimidine-ones by a one-pot three-component reaction

A new three-component reaction between salicylaldehydes, barbituric acid, pyrazolones, in the presence of para-toluenesulfonic acid, efficiently provides pyrazol-chromeno[2,3-d]pyrimidine-ones derivatives in good yields in ethanol/water at 70 °C. This multicomponent reaction showed high atom economy...

Zusammenfassung:A new three-component reaction between salicylaldehydes, barbituric acid, pyrazolones, in the presence of para-toluenesulfonic acid, efficiently provides pyrazol-chromeno[2,3-d]pyrimidine-ones derivatives in good yields in ethanol/water at 70 °C. This multicomponent reaction showed high atom economy. Graphical Abstract
