attractive approach to valuable yet synthetically challenging benzo[b]azepines was established via palladium(II)/Lewis acid cocatalyzed oxidative [5 + 2] annulation of readily available 2-alkenylanilines and propargylic esters. The protocol features mild reaction conditions and good functional group tolerance, constituting an array of benzo[b]azepines in yields of 30–75%.

A series of substituted derivatives of 2-amino-3-benzoylphenylaceticacid (amfenac) has been synthesized and evaluated for antiinflammatory, analgesic, and cyclooxygenase inhibiting activity. Several derivatives including 157 (4'-chloro), 158 (4'-bromo), and 182 (5-chloro, 4'-bromo) were more potent than indomethacin in these assays.
