2,3-Dimethylmaleic anhydride acts as a reagent in the preparation of maleimides. It is also employed as an amino group protecting agent for superoxide dismutase. Further, it serves as a reactant in the dissociation of ribosomal proteins. In addition to this, it is used in the preparation of dimethylmaleic acid dimethyl ester.
Does not undergo Diels-Alder reactions with furan, but does react with 1,3-Diphenylisobenzofuran, L00101, to give benzocantharadin: J. Org. Chem., 47, 4011 (1982).
The use of the dimethylmaleoyl (DMM) group has been investigated for amino group protection in oligosaccharide synthesis. The DMM group is introduced using triethylamine as base. It promotes ß -linkage by neighboring group participation and is stable to acids and non-nucleophilic bases. Cleavage can be brought about by treatment with dilute aqueous NaOH: Eur. J. Org. Chem., 2305 (1998).
