title: A Convenient One-Pot Route to Screw-Shaped [5]Azahelicenes via Rhodium(III)-Catalyzed Multiple C-H Bond Activation.
abstract: A convenient rhodium(III)-catalyzed cascade reaction of 7-azaindoles and alkynes through multiple C-H bond activation for the synthesis of unique [5]azahelicenes has been developed. The optical property of these screw-shaped helicene derivatives could be further utilized in electronic devices to recognize mercury ions.
