DETAILS

Description (English)
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.1
Packaging
