• Rapid and Efficient Trifluoromethylation of Aromatic and Heteroaromatic Compounds Using Potassium Trifluoroacetate Enabled by a Flow System
  作者：Mao Chen、Stephen L. Buchwald

  日期：2013.10.25

  Going to the source: The trifluoromethylation of aryl/heteroaryl iodides has been demonstrated using a flow system, thus enabling a rapid rate of reaction. A broad spectrum of trifluoromethylated compounds was prepared in good to excellent yields using CF3CO2K as the trifluoromethyl source. The process has the advantage of short reaction times and uses convenient [CF3] sources.

  Structually related to the known CK2 inhibitors, 2,6‐disubstituted pyrazine and 4,6‐disubstituted pyrimidine derivatives were synthesized and their inhibitory activities toward CK2α and CK2α′ were evaluated. Structure‐activity relationship study has revealed that several pyrazine derivatives bearing a (pyrrol‐3‐yl)acetic acid and a monosubstituted aniline possess potent inhibitory activities.
