An Iron-Catalyzed Cascade Approach to Benzo[b]carbazole Synthesis Followed by 1,4-Sulfonyl Migration

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,...

Description
Summary: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. It′s iron, man: A simple and straightforward approach was developed to obtain 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‐tosyl migration, tolerance of a variety of functional groups, good yields and an economic catalytic system.
