Abstract

Abstract A facile route to furan-3, 4-dicarboxylic acid is described. Dimethylmaleic anhydride (1) on NBS-bromination followed by aqueous KOH treatment gave bis (hydroxymethyl) maleic anhydride (3), which on intramolecular Mitsunobu ring closure followed by esterification and DDQ-oxidation furnished the desired esters of furan-3, 4-dicarboxylic acid 7a/b.
