Continuous flow photocyclization of stilbenes - scalable synthesis of functionalized phenanthrenes and helicenes.
A continuous flow oxidative photocyclization of stilbene derivatives has been developed which allows the scalable synthesis of backbone functionalized phenanthrenes and helicenes of various sizes in good yields.
