Boryl radical-mediated halogen atom transfer-induced radical cascade cyclization of N -( o -cyanobiaryl)acrylamides with alkyl halides

An alternative and general approach for nitrogen-containing polycyclic derivative formation by using halides, N -( o -cyanobiaryl)acrylamides and Me 3 N–BH 3 as a reagent for halogen-atom transfer under photocatalytic conditions is presented.
