In the presence of highly activated molecular sieves (4 A0), the Diels-Alder reactivity of in situ generated N-benzoylindole-2,3-quinodimethane is enhanced considerably. Reactions of this species with a variety of carbodienophiles give rise to novel functionalized and [b]annelated carbazole derivatives in a one-pot procedure.
