Halo substituent effects on intramolecular cycloadditions involving furanyl amides.

J. Org. Chem. 71 , 5432, (2006)

Intramolecular Diels-Alder reactions involving a series of N-alkenyl-substituted furanyl amides were investigated. Stable functionalized oxanorbornenes were formed in high yield upon heating at 80-110...
