A highly efficient and regioselective C-3-alkylation of 2-arylindoles with maleimides has been developed using Ag(I) as catalyst. 3-(2-Aryl-1H-indol-3-yl)pyrrolidine-2,5-diones were afforded with high yields (up to 97%) under relatively mild reaction conditions. The method features operational simplicity and avoiding external oxidant.

Key words: silver-catalyzed, 2-arylindoles, maleimides, alkylation
