An efficient synthesis of a variety of 6-alkylated phenanthridine via a cyclization reaction by photoredox catalysis between 2 and isocyanobiaryls and alkylborates is reported. A range of 2-isocyanobiaryls was tolerated well. This cyclization reaction displays excellent functional group tolerance and broad substrate scope, allowing access to desired products in good to excellent yields.
