8-(Methoxycarbonyl)octyl 3,6-di-O-(alpha-D-mannopyranosyl)-alpha-D-mannopyranoside (10) was synthesized in 54% yield by regioselective diglycosylation of unprotected mannoside 4, employing the trichloroacetimidate donor 1, followed by debenzoylation. Derivatives of compounds 4 and 10 were used to prepare conjugates containing fluorochromes for the study of carbohydrate-lectin interactions, as well
通过使用未保护的甘露糖苷4的区域选择性二糖基化反应,使用三氯乙酰胺基供体1,将8,(甲氧羰基)辛基3,6-二-O-(α-D-甘露吡喃糖基)-α-D-甘露吡喃糖苷(10)合成。然后进行脱苯甲酰化。化合物4和10的衍生物用于制备含荧光染料的缀合物,用于研究碳水化合物-凝集素的相互作用,以及与磷脂的缀合物,用于制备脂质体。
