Isoflavones were synthesized by two steps in good yields, starting from commercially available 2-hydroxyacetophenones and benzene analogs. First, intermediate 3-(dimethylamino)-1-(2-hydroxyphenyl) prop-2-en-1-ones were obtained by the condensation of 2-hydroxyacetophenones and DMF-DMA in DMF with high yields. Second, isoflavones were synthesized by(More)
5,6-Diarylpyrazolo[1,5-a]pyrimidines (3) and 6,7-diarylpyrazolo[1,5-a]pyrimidines (4) were chemoselectively synthesized by the condensation of isoflavone (1) and 3-aminopyrazole (2). 5,6-Diarylpyrazolo[1,5-a]pyrimidines (3) were obtained via microwave irradiation, and 6,7-diarylpyrazolo[1,5-a]pyrimidines (4) were obtained via conventional heating.

The direct coupling of 3-iodochromen-4-ones with heteroaromatics has been achieved via a photochemical reaction. A variety of 3-heteroarylchromones was obtained in moderate to good yields from the corresponding 3-iodochromen-4-ones and heteroaromatics, such as pyrrole, furan, thiophene, and benzofuran. The reaction worked smoothly in acetonitrile under a(More)
A new concise, facile method for synthesis of isoflavones was accomplished in moderate to good yields for 3-iodochromones or 3-bromochromones and arylzinc bromides via Negishi cross-coupling reaction catalyzed by $$\hbox {NiCl}_{2}/\hbox {PPh}_{3}$$ NiCl 2 / PPh 3 or $$\hbox {NiCl}_{2}(\hbox {PPh}_{3})_{2}$$ NiCl 2 ( PPh 3 ) 2 at room temperature.
