• 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 ? -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).
