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.
