1-ACYL-2,3-DIHYDROXYINDOLINES : A REINVESTIGATION
Harrison, David M.
, p. 6063 - 6064 (1984)
Per-acid oxidation of 1-acylindoles in aqueous dioxan furnished the title compounds which exist in equilibrium with their keto-amide isomers in solution.The so-called trans 1-benzoyl-2,3-dihydroxy-2,3-dimethylindoline was shown to be 1-acetyl-2,3-dihydrox
