Flavones and isoflavones are recognized as privileged heterocyclic scaffolds for the preparation of bioactive compounds.Efficient methods to access these heterocycles are in urgent need.Herein,we report diversity-orie...
A simple method for the cyclocondensation of substituted isoflavones with cyanoacetamide in the presence of sodium hydroxide to give an array of 3-cyano-5,6-diarylpyridin-2(1H)-ones in good yields is reported.
Microwave irradiation was used to accelerate the cyclocondensation of i soflavones and 5-amino-1H-imidazole- 4-carboxamide in the presence of sodium hydroxide to produce 3,4-diphenyl-imidazo[ 1,5-a]pyrimidines in good...
