✦ Synopsis

In presence of bismuth (III) chloride, a carbonylated electrophile (ethyl mes oxalate or glyoxylate) and usual diene led selectively (65 to 100%) the hetero carbonyl-Diels-Alder reaction with the ene reaction product. BiCl 3 exhibits strong catalytic activity and, compared with previous literature, reacts under mild conditions.

BiCl 3 efficiently catalyzed the intramolecular hetero-Diels-Alder reactions of aldimines generated in situ from aromatic amines and the N-allyl derivative of o-aminobenzaldehyde in refluxing acetonitrile to afford a novel class of hexahydrodibenzo [b,h][1,6]naphthyridine derivatives. The products a
