Abstract: A one-pot and efficient three-component reaction of indoles, acrylates and maleimides for the synthesis of pyrrolo[3,4-a]carbazole-1,3-dione derivatives was developed. Three C-C bonds and one ring were created in a single step via an indole-to-carbazole transformation triggered by Pd(Ⅱ)-catalyzed direct C3-alkenylation of indoles.

Key words: Carbazole, One-pot, Tandem reaction, Three-component reaction, Indole-to-carbazole
