Notes:
Two pyruvated galactosyl donors, 2,3-di-O-benzoyl-4,6-O-[1-(R)-methoxycarbonyl(ethylidene)]-α-D-galactopyranosyl chloride (6) and trichloroacetimidate 13, were coupled to position 3 of suitably protected mono and disaccharide benzyl glucoside acceptors. For both donors, an unusual high content of the α-(1 → 3)-linked products was obtained. The corresponding β-(1 → 3)-linked di- and trisaccharides are related to exopolysaccharides of Rhizobium leguminosarum.
