Anwendungen

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.

Bemerkungen

Moisture sensitive. Incompatible with strong oxidizing agents, strong acids and strong bases.

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).
