Rh(III)-Catalyzed Direct ortho Alkylation of Carbazoles with Nitroalkenes

The Rh(III)-catalyzed ortho alkylation of N-pyridylcarbazoles with nitroalkenes has been developed, furnishing a wide range of 2-(2nitroalkyl)carbazoles. Both aromatic and aliphatic nitroalkenes participated in this alkylation reaction successfully. This protocol also proceeded well with an indoline based substrate. Derivatization of the representative nitroalkane product was described.
