摘要:
Acetylation of 2-methyl-1-phenylsulfonylindole with an excess of aluminium chloride and acetic anhydride afforded exclusively 6-acetyl-3-chloro-2-methylindole and 6-acetyl-3-chloro-2-methyl-1-phenylsulfonylindole.

The synthesis of polysubstituted indoles is described by the domino reaction of 2-haloanilines and 1,3-dicarbonyl compounds, 1,3-diketones, β-keto esters and β-keto amides, using copper catalysis under ligand-free conditions. The protocol provides a simple, general and atom economical process for the synthesis of substituted indoles at moderate temperature.
