A fluorescent derivative of sulfatide, labeled with a dansyl probe at position 6 of galactose, was prepared through a glycosylation reaction between a 6-O-functionalized galactose donor and 3-O-benzoyl-azidosphingosine. The sphingoid acceptor was obtained in high yield through exploitation of a highly stereoselective nucleophilic addition of pentadecyne to 2,3-O-cyclohexylidene-D-glyceraldehyde. The
通过 6-O-功能化的半乳糖供体和 3-O-苯甲酰基-叠氮基鞘氨醇之间的糖基化反应,在半乳糖的 6 位用丹酰探针标记了硫苷脂的荧光衍生物。通过利用十五炔与 2,3-O-亚环己基-D-甘油醛的高度立体选择性亲核加成,以高产率获得了鞘氨醇受体。荧光硫苷脂与可溶性重组人 CD1a 结合,是研究 CD1 抗原结合特性的宝贵工具。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
