Ultrasound assisted Mizoroki–Heck reaction catalyzed by Pd/C: Synthesis of 3-vinyl indoles as potential cytotoxic agents
Abstract
The Pd/C–PPh3 catalyst system facilitated the C–C bond forming reaction between 3-iodo-1-methyl-1H-indole and various terminal alkenes under ultrasound irradiation. The present ultrasound assisted Mizoroki–Heck coupling afforded a number of 3-vinyl indole derivatives in good to acceptable yields. Two of these indole derivatives showed cytotoxic activities against breast cancer cell lines. Keywords: Indole, Alkenes, Pd/C, Ultrasound, Cytotoxicity
