Anhydrous indium trichloride (InCl3) is found to catalyze the imino Di
els-Alder reactions of Schiffs bases with cyclopentadiene, cyclohexen-
2-one and cyclohepten-2-one which resulted in facile synthesis of cycl
opentaquinolines, azabicyclooctanones and previously unreported series
of azabicyclononanones. (C) 1998 Elsevier Science Ltd. All rights res
