Table 2 Substrate scope of oxidative rearrangement of tetrahydro-β-carbolines

From: Green oxidation of indoles using halide catalysis

  1. aThe reaction was carried out in THF/AcOH/H2O (1:1:1) at room temperature for 0.5–20 h
  2. b The minor diastereomer could not be obtained and the diastereomeric ratio was determined by 1H-NMR analysis of the crude reaction mixture
  3. c10 mol% KBr was used
  4. dAdditional 0.6 equivalent of oxone was added after 12 h reaction
  5. eIsolated diastereomeric ratio
