| Abstract: | The photochemical synthesis of benzoa]carbazoles from easily synthesizable 2‐aryl‐3‐(1‐tosylalkyl)indoles is presented. Irradiation of these substrates in polar aprotic solvents (acetone or THF) gives selectively the target products in satisfactory yields. This versatile and efficient procedure promises to be a useful alternative to the multistep strategies reported in the literature. |
