Syntheses of 1-alkyl-2-acylindoles, 1-alkyl-2-acylindole-3-carboxylic acids, and their esters, in superbasic media
2-Acylindoles and 2-acylindole-3-carboxylic acids are readily alkylated at the nitrogen atom by haloalkanes in a superbasic medium (DMSO + NaOH). For the carboxylic acids, this reaction may proceed either entirely at the nitrogen atom, or at both the the

Rearrangement Of 1-Indole-2,3-Dione To Form 2-Acylindolyl-3-Carboxylic Acid
It has been shown that 1-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.
