  Diels-Alder Reactions under Molecular Sieve Catalysis: Enhancement of Reactivity in Cyclization Reactions with N-Benzoylindole-2,3-quinodimethane to Functionalized Carbazoles

  摘要：

  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.

  The Diels-Alder reactivity of in situ generated N-benzoylindole-2,3-quinodimethane has been expanded considerably to include reactions with carbon- and hetero-dienophiles which furnish a variety of [b]annellated indoles as well as functionalized and annellated carbazoles. The frontier molecular orbital theory was found to be a useful model for the prediction of the experimental results under consideration of reactivity aspects.
