“…Visible light is a plentiful, clean and renewable source of energy that provides a powerful and environment friendly alternative to conventional methods. [18][19][20] For organic transformations, it uses easily accessible and affordable photocatalysts such as organic dyes. [21] Similarly, electro-organic synthesis is acknowledged as a potent, sustainable and ecologically friendly method in organic synthesis.…”

An efficient and facile strategy for the synthesis of 6‐(sulfonylmethyl)phenanthridines and its derivatives has been developed via tandem sulfonylation cyclization of vinyl azides under mild conditions in the absence of any catalysts and additives. The reaction simply utilizes easily accessible and cheap K2S2O5 as the sulfur dioxide source, delivering functionalized phenanthridines in moderate to excellent yields with operational simplicity and gram‐scale synthesis, as well as good functional‐group tolerance.
