Visible-light-promoted cascade cyclization of N-arylacrylamides with bromomethyl aryl sulfone: Access to sulfonylmethylated phenanthridines

We present a visible-light-promoted radical cascade cyclization reaction via sulfonylmethylation, cyano insertion, and radical cyclization of unactivated alkenes bearing cyano groups. This strategy enables the rapid synthesis of sulfonylmethylated phenanthridines...
