Anhydrous indiumtrichloride (InCl3) is found to catalyze the imino Diels-Alderreactions of Schiff's bases with cyclopentadiene, cyclohexen-2-one and cyclohepten-2-one which resulted in facile synthesis of cyclopentaquinolines, azabicyclooctanones and previously unreported series of azabicyclononanones.

ABSTRACT Urea nitrate is found to be an efficient catalyst for the imino Diels-Alder reaction of aldimines with cyclopentadiene, 3,4-dihydropyran and dihydrofuran is reported for the first time. One pot synthesis of cyclopentaquinolines from benzaldehyde, aromatic amines with cyclopentadiene catalyzed by urea nitrate is also reported.
