Enzymic and nonenzymic intramolecular acyl migrations in partially pivaloylated monosaccharides

Acid or base catalyzed intramolecular migrations of acyls in sugar molecules are well known and the possible mechanism of these transesterifications has been described. We report on sponaneous pivaloyl group migrations in partially pivaloylated mannose and xylose series of sugars in aqueous solvents. Furthermore, using the same substrates, we describe pivaloyl migrations caused by enzymes present in some mammalian sera.
