Abstract: A new class of bis and tris heterocycles–pyrazolyl indoles and thiazolyl pyrazolyl indoles were prepared from the Michael acceptor (E)-3-(1H-indol-3-yl)-1-arylprop-2-en-1-ones by ultrasound irradiation technique and tested for antioxidant activity. The thiazolyl pyrazolyl indoles and pyrazolyl… read more here.
