The first intermolecular Friedel-Crafts acylation of a variety of aromatic substrates with azetidinones is described. The Friedel-Crafts acylations are performed under very mild conditions, using trifluoromethanesulfonic acid to produce beta-amino aromatic ketones in excellent yields.

N-Protected and unprotected 2-azetidinones, protolytically activated by superacidic trifluoromethanesulfonic acid, react with aromaticcompounds to give β-amino aromatic ketones in good to excellent yields (65–98%). Non-benzenoidaromatics (pyrrole and ferrocene) produced good yield (64–89%) of the corresponding ketones.
