Rearrangement of 1-[2-oxoalkyl(aryl)]indole-2,3-dione to form 2-acylindolyl-3-carboxylic acid
It has been shown that 1-[2-oxoalkyl(aryl)]indole-2,3-diones are recyclized under the influence of sodium alcoholate to form 2-acylindolyl-3-carboxylic acids. A reaction scheme is proposed for this rearrangement.
