Abstract
A series of heterocycle-substituted acetophenones were prepared and reacted with the Brønsted superacid CF3SO3H (triflic acid=trifluoromethanesulfonic acid). Cyclodehydration provided aryl-substituted imidazo[2,1-a]isoquinolines and related products (28–85%, seven examples). A mechanism is proposed involving dicationic intermediates.
