Compounds and compositions for prodrugs useful for the oral and parenteral delivery of amine-containing drugs, amino acids, and peptides are described. Compounds containing biologically-active amino groups are conjugated to a lipophilic derivative through an amide bond in order to facilitate transport of the conjugate through the cell membrane. Methods of coupling a biologically-active molecule containing at least one amine functional group to a lipophilic anhydride are also described.

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.
