  • Synthesis of Core-class 2<i>O</i>-Linked Glycopeptides: a Benzyl-protected Tetrasaccharyl Serine and its Derivative Carrying a Hydrophobic Cholestanyl Group
    作者:Jun WATABE、Latika SINGH、Yuko NAKAHARA、Yukishige ITO、Hironobu HOJO、Yoshiaki NAKAHARA

    日期:2002.1
    A core-class 2 tetrasaccharide-linked serine was synthesized in a convergent manner. The coupling reaction of disaccharide glycosyl donor 3 and acceptor 4 stereoselectively afforded tetrasaccharide 15, which was converted to glycosyl fluoride 20. Glycosylation of Fmoc serine allyl ester 5 with 20 produced α- and β-glycosides in 40% and 33% yields, respectively. α-Isomer 21 was converted into 1, a useful building block for the solid-phase synthesis of glycopeptides. On the other hand, 21 was N-deprotected and condensed with hydrophobic cholestanol through a succinyl spacer. The same compound was alternatively synthesized by coupling 20 and 28. Functional group manipulation and hydrogenation afforded core 2 tetrasaccharide-cholestanol conjugate 2.
    一种核心类2的四糖链接丝氨酸以汇聚方式合成。双糖糖基给体3与受体4的偶联反应立体选择性地合成了四糖15,随后将其转化为糖基氟化物20。用20对Fmoc丝氨酸烯丙酯5进行糖基化反应分别以40%和33%的产率得到了α-和β-糖苷。α异构体21被转化为1,这是固相合成糖肽的有用构建模块。另一方面,21进行了N-脱保护,并通过琥珀酰间隔基与疏水的胆固醇醇缩合。同样,该化合物也可通过20与28的偶联反应来合成。功能基团的操控和氢化得到了核心2四糖-胆固醇醇结合物2。

    alNAc-(1→3)-l-Ser/Thr building blocks for solid-phase synthesis of glycopeptide were stereoselectively synthesized in a benzyl-protected form. The key glycosylation reaction to form β-d-GlcNAc linkage was established by the use of protected N-trichloroacetyl-d-lactosaminyl fluoride. Usefulness of the building block was demonstrated by solid-phase synthesis of a segment of human leukosialin. Benzyl
    β-d-Gal-(1→4)-β-d-GlcNAc-[β-d-Gal-(1→3)]-α-d-GalNAc-(1→3)-l-Ser / Thr构建以苄基保护的形式立体选择性地合成糖肽的固相合成嵌段。形成β-d-GlcNAc键的关键糖基化反应是通过使用受保护的N-三氯乙酰基-d-乳糖胺基氟化物建立的。该构建基的有用性通过人类白细胞唾液酸蛋白片段的固相合成证明。通过“低酸度TfOH”条件可有效去除苄基保护基。

    derivative 35 carrying a 3-O-allyl protecting group at the Gal residue by reiterative glycosylation using the (N-phenyl)trifluoroacetimidate method. Decasaccharide 50 was used as a building block in the solid-phase synthesis of a MUC1-related glycopeptide. Synthetic glycopeptide was obtained through two acidic processes: cleavage from resin with reagent K at a lowered temperature and debenzylation with
    描述了一种新的四糖胺基O-糖氨基酸的合成方法。通过2-三氯乙酰氨基基团辅助的β-糖基化进行乳糖胺基单元的立体选择性组装。由于涉及除去4- O-氯乙酰基的步骤中的低收率,对合成十糖苏氨酸2的初步研究显示出有限的成功。相反,使用(N-苯基)三氟乙酰亚氨酸酯方法通过反复糖基化,由在Gal残基上带有3- O-烯丙基保护基的关键LacNAc衍生物35有效地合成了4- O-苄基化的十糖基苏氨酸50。十糖50用作MUC1相关糖肽的固相合成的基础。合成的糖肽是通过两个酸性过程获得的:在较低的温度下用试剂K从树脂上裂解,然后用低酸度TfOH的稀释混合物进行脱苄基作用。分离了所需的糖肽54作为主要产物,而由于β-GlcNAc糖苷键的酸不稳定特性,产生了一系列缩短糖类的次要产物。

    tetrasaccharide building blocks (1a/1b) for solid-phase synthesis of glycopeptide were synthesized via stereoselective glycosylation of the disaccharyl Ser/Thr (3a/3b) with a glycosyl fluoride (2) carrying the 2-trichloroacetamido group that was readily converted into a 2-acetamido group by reduction. A segment of glycoprotein leukosialin (215–224) was synthesized by the solid-phase protocol, the building block (1b)
    固相合成糖肽的核心2型四糖结构单元(1a / 1b)是通过二糖基Ser / Thr(3a / 3b)与带有2-三氯乙酰胺基的糖基氟化物(2)的立体选择性糖基化合成的。通过还原容易地将其转化为2-乙酰氨基基团。固相规程合成了糖蛋白白蜡蛋白(215-224)的一个片段,即构件(1b)被利用。用试剂K从树脂上切割合成糖肽,然后用“低酸度TfOH”混合物对产物进行处理,促进了苄基的完全除去,糖苷键的损失最小。通过使用特定的唾液酸转移酶,以非常高的效率将N-乙酰神经氨酸(唾液酸)残基酶促地引入到去保护的糖肽(21)中。
