  A Convenient Synthesis of 2-Arylthiochromen-4-ones (Thioflavones) by Iodine-Mediated Cyclization of 3-Aryl-1-[2-(1,1-dimethylethylsulfanyl)phenyl]prop-2-en-1-ones

  摘要：

  A convenient two-step synthesis of 2-arylthiochromen-4-ones (thioflavones) beginning with 1-[2-(1,1-dimethylethylsulfanyl)phenyl]ethanones is described. Thus, 3-aryl-1-[2-(1,1-dimethylethylsulfanyl)phenyl]prop-2-en-1-ones were prepared by the condensation of 1-[2-(1,1-dimethylethylsulfanyl)phenyl]ethanones with aromatic aldehyde in the presence of sodium hydroxide, and were treated with iodine in refluxing N-methylpyrrolidin-2-one (NMP) or propanenitrile to afford the desired products in moderate to fair yields.
