Reaction of Indole-2,3-dicarboxylic Anhydride with Grignard Reagents: Synthesis of 2-Acylindoles
摘要:
Reaction of indole-2,3-dicarboxylic anhydride with methylmagnesium bromide and phenylmagnesium bromide gave 2-acetyl- and 2-benzoyl-indole-3-carboxylic acids, but with tert-butylmagnesium chloride, 3-pivaloylindole-2-carboxylic acids were obtained as the main products. Treatment of 2-acylindole-3-carboxylic acids with copper chromite in quinoline or potassium hydroxide gave the corresponding 2-acylindoles.
