A facile catalyst-free one-pot three-component reaction of dimedone, 3-methyl-5-pyrazolone, and arylglyoxals: Synthesis of substituted chromeno[2,3-c]pyrazolones
The synthesis of substituted chromeno[2,3-c]pyrazolones 4 through a one-pot three-component condensation reaction between dimedone 1, arylglyoxals 2, and 3-methyl-5-pyrazolone 3 in DMF under reflux conditions without using any catalyst is reported. All the products were obtained in excellent yields...
