Bi(OTf)3-catalysed prenylation of electron-rich aryl ethers and phenols with isoprene: A direct route to prenylated derivatives
Electron-rich aryl ethers and phenols react with isoprene (2-methylbuta-1,3-diene) in the presence of catalytic Bi(OTf)3 at 40 °C to afford the corresponding prenylated or 2,2-dimethylchroman products, respectively, in moderate to good yields.
