Application
Used in a study of the effect of a furanyl halo-substituent on the intramolecular Diels-Alder reaction between the furan ring system and a pendant allylamide. The yield of the cycloaddition is improved with a C-5 bromide vs -chloro or -unsubstituted furan.

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 degrees C. The cycloaddition reactions include several bromo-substituted furanyl amides, and these systems were found to
