title: Aza-Nazarov cyclization cascades.
abstract: Benzamides with tethered acetal groups undergo reactions in CF(3)SO(3)H to give ring-fused isoindolinones by a cyclization cascade. The reaction initially forms an N-acyliminium ion which then gives the isoindolinone by the aza-Nazarov reaction. An unusual variant also cyclizes at the allylic position.
