摘要
The p-trifluoroacetamidophenylethyl β-glycoside 9 of the trisaccharide 0-(2-acetamido-2-deoxy-β-D-galactopyranosyl)-(l—4)-0-P*D-galactopyranosyl-(l-»4)-D-glucopyranose (gangliotriose, asialo-GM2) was synthesised. The key step was coupling of a suitably protected lactose derivative with a galactosamine thioglycoside derivative using sulfuryl chloride/trifluoromethanesulfonic acid activation. © 1990, Taylor & Francis Group, LLC.
