An efficient regioselective C-3 acylation of free indoles (N-H) has been accomplished via oxidative decarbethoxylation of easily available ethyl arylacetates using Cu(OAc)2 and KOtBu in DMSO.

A simple and efficient strategy for the preparation of 3-acylindoles via visible-light promoted C3-acylation of free (NH)- and N-substituted indoles with α-oxocarboxylic acids was developed. The reaction tolerates a wide range of functional groups, and the corresponding 3-acylindoles were obtained in high yields under mild conditions.

An efficient Cu-catalyzed decarboxylative C3-acylation of free (N-H) indoles using α-oxocarboxylic acids as acylating agents has been developed. This method was compatible with a variety of functional groups and provided an attractive alternative access to 3-acylindoles in moderate to high yields.
Temperature-dependent product selectivity in the Vilsmeier-Haack reaction on bis(phenylhydrazones) of bis(aroylmethyl) sulfides (=1,1'-[thiobis(methylene) ]bis[arylmethanone] bis(2-phenylhydrazones)): Synthesis of 3-aroylindoles (=aryl(1H-indol-3-yl)methanones)

The bis(phenylhydrazone) of substituted diphenacyl sulfides (=1,1'-[thiobis(methylene)]bis[arylmethanone] bis(2-phenylhydrazones)) 1 underwent a tandem sequence of reactions upon treatment with Vilsmeier reagent, ultimately yielding 3-aroylindoles (=aryl(1H-indol-3-yl)methanones) 3 (Scheme 1 and Table 1). The reaction seems to be product selective depending upon the reaction temperature. Copyright
A novel microwave-irradiated solvent-free 3-acylation of indoles on alumina
Lai, Qiu Yu,Liao, Rong Su,Wu, Shao Yong,Zhang, Jia Xin,Duan, Xin Hong

A simple and efficient 3-acylation of indoles under microwave-heated and solvent-free conditions is developed. This general procedure uses neutral Al2O3 as a new, green and reusable catalyst giving good to high yields within short reaction times. Utilizing such an environmentally- benign methodology, a variety of indoles bearing electron-releasing or electron-withdrawing groups were conveniently acylated.
