  here an efficient regioselective protection strategy for xylose with two-step successive protections on 4- and 2-OH. This method enables the expeditious preparation of various xylose building blocks (3a–c, 5, 6). The rapid selective 2,4-protection especially facilitates the synthesis of 3-substituted xyloside structures. By this approach, typical arabino-α-1,3-xyloside disaccharide and trisaccharide

  我们在这里报告了一种有效的木糖区域选择性保护策略，对4-和2-OH进行了两步连续的保护。此方法允许在不同木糖积木迅速制备（图3a - ç，5，6）。快速的选择性2，4-保护尤其促进了3-取代的木糖苷结构的合成。通过这种方法，已经成功地合成了典型的阿拉伯糖α-1,3-木糖苷二糖和三糖作为阿拉伯木聚糖的片段结构单元。

  The synthesis of a compound containing a 4-nitrocatechol bound to two vicinal alpha-L-arabinofuranosyl moieties through a linker arm was achieved using a sulfate protecting group to facilitate selective alkylation of one aromatic hydroxyl. Several alpha-L-arabinofuranosidases displaying different selectivities were tested and a simple microtiter plate-based assay was developed. The observed resistance of the compound to alpha-L-arabinofuranosidase-mediated hydrolysis makes it suitable for the identification of enzymes that are able to accommodate bis-arabinofuranosylated moieties.
