N-H Carbazole Synthesis from 2-Chloroanilines via Consecutive Amination and C−H Activation

N-H carbazoles can be produced from 2-chloroanilines and aryl bromides via consecutive catalytic amination and C−H activation. In many instances, this can be done in a tandem manner in one pot. The methodologies developed can be used in the synthesis of a range of carbazoles, including the natural products Clausine P and glycozolidine and a precursor in the synthesis of Clausines H, K, O, and 7-methoxy-O-methylmukonal, and can be extended to the synthesis of indoles.
