Continuous flow photocyclization of stilbenes – scalable synthesis of functionalized phenanthrenes and helicenes

Abstract

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.
