The reaction of sulfonylpyrroles with nitroalkanes in the presence of KF/alumina generates 3‐(2‐nitroalkyl)pyrroles in good yields. These compounds can be converted into trisubstituted 6‐azaindoles by a sequence of reactions comprising reduction of the nitro group, Pictet–Spengler cyclization and final oxidative aromatization.
