  以磷酸糖基和二硫代磷酸三酯为糖基化剂的寡糖合成

  摘要：

  描述了通过 1,2-脱水糖从糖基中高效地一锅合成α-和β-糖基磷酸酯和二硫代磷酸三酯。糖基磷酸酯用作多功能糖基化剂，用于合成 β-葡糖苷、β-半乳糖苷、α-岩藻糖苷、α-甘露糖苷、β-葡糖醛酸和 β-葡糖胺键，在用三甲基甲硅烷基三氟甲磺酸酯 (TMSOTf) 活化后。除了作为 O-糖基化的有效供体，糖基磷酸酯还可有效制备 S-糖苷和 C-糖苷。此外，还讨论了糖基磷酸酯与甲硅烷基化受体的酸催化偶联。糖基二硫代磷酸酯被合成并且也用作糖基供体。这种替代方法提供了与含有糖基的受体的兼容性，以形成 β-糖苷。为了最大限度地减少保护基团的操作，报告了使用糖基磷酸酯的正交和区域选择性糖基化策略。描述了一种正交糖基化方法，包括在硫糖苷受体存在下激活磷酸糖基供体，以及受体介导的区域选择性糖基化策略。此外，公开了利用α-和β-糖基磷酸酯反应性差异的独特糖基化策略。此处概述的程序为在溶液中组装复杂寡糖以及通过单

  Linear Synthesis of the Tumor-Associated Carbohydrate Antigens Globo-H, SSEA-3, and Gb3

  摘要：

  The tumor-associated carbohydrate antigens Globo-H, SSEA-3, and Gb3 were synthesized in a linear fashion using glycosyl phosphate monosaccharide building blocks. All of the building blocks were prepared from readily available common precursors. The difficult alpha-(1-->4-cis)-galactosidic linkage was installed using a galactosyl phosphate donor with high selectivity. Introduction of the beta-galactosamine unit required the screening a variety of amine protecting groups to ensure good donor reactivity and protecting group compatibility. An N-trichloroacetyl-protected galactosamine donor performed best for the installation of the beta-glycosidic linkage. Conversion of the trichloroacetyl group to the N-acetyl group was achieved under mild conditions, fully compatible with the presence of multiple glycosidic bonds. This synthetic strategy is expected to be amenable to the synthesis of the globo-series of tumor antigens on solid-support.

  Described is an efficient one-pot synthesis of alpha- and beta-glycosyl phosphate and dithiophosphate triesters from glycals via 1,2-anhydrosugars. Glycosyl phosphates function as versatile glycosylating agents for the synthesis of beta-glucosidic, beta-galactosidic, alpha-fucosidic, alpha-mannosidic, beta-glucuronic acid, and beta-glucosamine linkages upon activation with trimethylsilyl trifluoromethanesulfonate
