title: An iron-catalyzed cascade approach to benzo[b]carbazole synthesis followed by 1,4-sulfonyl migration.
abstract: A simple and straightforward approach was developed to construct 5H-benzo[b]carbazole derivatives by iron catalysis in a cascade sequence. The notable features of this work include an atom-economical cascade sequence, unprecedented 1,4-sulfonyl migration, tolerance of a variety of functional groups, good yields, and an economical catalytic system.
