Electrosynthesis of fluorinated indole derivatives
摘要:
Anodic fluorination of various N-acetyl-3-substituted indole derivatives was successfully carried out in Et(4)NF-4HF/MeCN to provide the corresponding trans-2,3-difluoro-2,3-dihydroindoles exclusively or selectively. Treatment of difluorinated products with a base provided monofluoroindole derivatives or monofluoroindoline derivative depending on the substituents at the 3-position. (C) 2010 Elsevier Ltd.
