3-Furoic acid can be used as a reactant to synthesize:
- Furan-2,5- and furan-2,4-dicarboxylic acid under solvent-free conditions via disproportionation reaction.
- (±)-Hyperolactone A by reacting with 2-methylbutanal.
- Furo[2,3-b]pyridin-4-one-5-carboxylate ester derivatives as potential non-nucleoside inhibitors of human herpesvirus polymerases.
