Sulfated mono- and disaccharides were synthesised by a novel sulfation method via regioselective activation of the saccharides to their dibutyltin stannylene acetals, followed by treatment with sulfur trioxidetrimethylamine. This methodology was applied to the synthesis of 3′-sulfated lactosides 15 and 23, galactosylceramide sulfatide 3 and 2′-sulfated maltosides 30, 32 and 34.
硫酸化的单-和二糖是由一种新的硫酸化的方法合成经由糖类它们二丁基锡stannylene缩醛的区域选择性活化,随后用硫trioxidetrimethylamine治疗。该方法学应用于3'-硫酸化的乳糖苷15和23,半乳糖基神经酰胺硫化物3和2'-硫酸化的麦芽糖苷30、32和34的合成。
