Direct Assembly of Benzo[<i>a</i>]carbazole‐5‐carboxylates via a Diels–Alder Reaction with Arynes and 3‐Alkenylindoles

Abstract

Abstract A concise and direct synthetic strategy for the construction of benzo[ a ]carbazole‐5‐carboxylates has been disclosed via the Diels–Alder reaction of arynes and 3‐alkenylindoles. The reaction is highly selective and affords the benzo[ a ]carbazole‐5‐carboxylates in good‐to‐excellent yields.
