Abstract :
A convenient method for the selective differentiation of the 2-OH and 3-OH of pyranosides, based on the CsO2CCF3- or Ag2O-mediated acyl migration, has been established. The 2-OH and 3-OH can be sequentially glycosylated by the desired carbohydrate generating disaccharides of biological interest. A mechanism involving either acid- or base-assisted acyl migration is proposed.
