A visible-light-mediated tandem sulfonylation/cyclization of vinyl azides with sulfonyl
hydrazines was developed that provides an efficient and simple strategy for the synthesis
of valuable 6-(sulfonylmethyl)phenanthridines with a broad substrate scope and satisfactory
yields under mild conditions.
Key words
