IRONic electrophilicindoles! The C3‐regioselectivehydroarylation of N‐acetyl indoles with aromatic nucleophiles mediated by FeCl3 features a rare example of the electrophilic reactivity of the indole core in a Friedel–Crafts reaction. This indole umpolung allows us straightforward access to the tetracyclic benzofuroindoline motif found in the natural product diazonamide A, which is a potent antitumor
