2,3-Dibromofuran-5-carboxylic acid Usage And Synthesis

Uses	2,3-Dibromofuran-5-carboxylic acid is 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.
