The title trisaccharide and tetrasaccharidemoieties have been synthesized as part of our research programme to construct the complex triterpenoid saponin QS-21, a potentimmunoadjuvant, which has been used in a series of clinical immunization trials. In view of the unwillingness of glucuronic acid as glycosyl acceptor, the branched glucuronic acid-containing trisaccharide 20 was synthesized from D-glucose
