  One-Pot Synthesis of 2,3-Disubstituted Benzo[b]thiophene Derivatives from 2-Mercaptophenyl Ketones

  摘要：

  2-Mercaptopheryl ketones have been found to react with activated alkyl bromides (BrCH(2)EWG's), such as bromoacetates, bromoacetonitrile, and bromomethyl phenyl ketone, in the presence of two molar amounts of sodium hydride in THF at 0 degrees C to afford 2,3-disubstituted benzo[b]thiophenes in generally good to excellent yields.
