Substituted phenanthridines, such as the natural product trispheridine, have been accessed by the practical photochemical cyclization of N-benzylanilines. Functionalities, with a focus on fluoro substituents and protected catechols, are well tolerated on both the A and C rings. The phenanthridines were accessed in good to very good yields (up to 95 %) from iodinated substrates, whereas brominated substrates performed poorly in comparison (0-48 %).
