  Diverse Methyl Sulfone-Containing Benzo[b]thiophene Library via Iodocyclization and Palladium-Catalyzed Coupling

  摘要：

  Parallel solution-phase methods for the synthesis of a 72-membered benzo[b]thiophene library are reported. Medicinally interesting, drug-like, methyl sulfone-substituted benzo[b]thiophenes have been prepared by the palladium-catalyzed substitution Of 3-iodobenzo[b]thiophenes by Suzuki-Miyaura, Sonogashira, Heck, carboalkoxylation, and aminocarbonylation chemistry, The key intermediates for library generation, methyl sulfone-containing 3-iodobenzo[b]thiophenes, are readily prepared by iodocyclization and oxidation methodologies from readily available alkynes.
