One-Pot Access to Sulfonylmethyl Arylpyrroles via the Domino Aerobic Wacker-Type Aminocyclization/1,4-Sulfonyl Migration

PdCl2/CuCl2/NH4OAc-mediated the domino aerobic Wacker-type aminocyclization of α-allyl-β-ketosulfones 4 in cosolvents THF and MeOH afforded 2-(sulfonylmethyl)­arylpyrroles 5 via 1,4-sulfonyl migration with moderate to good yields.
