3-phenol-1H-pyrazoles (2), 4-halogeno-3-phenol-1H-pyrazoles (3) and 2-(1-phenol-1H-pyrazol-5-yl)phenols (4) were prepared by the condensation of (E)-3-(dimethylamino)-1-phenylprop-2-en-1-ones and hydrazine hydrate or phenylhydrazine in good yields. They were evaluated against five phytopathogens fungi, namely Cytospora sp., Colletotrichum gloeosporioides,(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.
