Abstract
N-Protected and unprotected 2-azetidinones, protolytically activated by superacidic trifluoromethanesulfonic acid, react with aromatic compounds to give small β-amino aromatic ketones in good to excellent yields. Non-benzenoid aromatics (pyrrole and ferrocene) produced good yield of the corresponding ketones.
