A novel and simple organoselenium-involved 7-membered cyclization method has been developed for accessing diverse seleno-benzo[b]azepines. The protocol involves an electrophilic cyclization process and is conducted under mild conditions. Mechanistic discussions rationalize the observed regioselectivity in the transformation. Further studies on the transformation of seleno-benzo[b]azepines and large-scale experiments demonstrate promising utility of this methodology.
