Abstract
We present here a convenient synthesis of the dibenzo[a,c]carbazoles via oxidative [4+2] Diels‐Alder cycloaddition of 2‐phenyl‐1H‐indoles with benzynes. The features of this protocol include the use of readily available raw materials, molecular oxygen as the oxidant, it being free of transition‐metal‐catalyst, and convenient method for the preparation of π‐extended dibenzo[a,c]carbazoles.
