Abstract
O-(6-O-Benzoyl-beta-D-galactopyranosyl)-(1-->4)- and O-(2,3,4-tri-O-ac etyl-beta-D-galactopyranosyl)- enzyloxycarbonyl-1,5-dideoxy-1,5-imino- D-glucitols (4 and 12) were each coupled with methyl (methyl 5-acetami do-4,7,8, 9-tetra-O-acetyl-3, 2-thio-D-glycero-D-galacto-2-nonulopyran osid)onate (5) in acetonitrile medium in the presence of dimethyl(meth ylthio)sulfonium triflate (DMTST) or N-iodosuccinimide/trifluoromethan esulfonic acid to give the corresponding alpha-sialyl-(2-->3)- and alp ha-sialyl-(2-->6)-glycosides (6 and 13 alpha), which were converted to novel ganglioside GM3-related trisaccharides (9 and 15) containing N- methyl-1-deoxynojirimycin.
