一种β-葡萄糖醛酸苷酶沉淀型荧光底物合成方法
摘要：
本发明公开了一种基于2-(苯并噻唑-2'-基)-4-溴苯酚的β-葡萄糖醛酸苷酶沉淀型荧光底物合成方法。该合成方法包括以下三步反应：1)糖基化反应；2)芳环化反应；3)脱保护基反应。该合成方法中每一步反应产率均可达中等以上，最高超过90％，价格或制备成本相对高的物料反应转化率相对较高，三步总产率可达37％，而且反应条件温和，易于实施。同时该合成方法中的糖基化反应步骤和脱保护基反应步骤可应用于以4-甲基伞形酮为糖基受体合成常见荧光底物4-甲基伞形酮基-β-D-葡萄糖醛酸苷，两步反应产率分别可达51％、89％，总产率可达约45％。
摘要（英）：

The invention discloses a synthesis method for a Beta-glucuronidase precipitation type fluorometric substrate based on 2-(benzothiazole-2'-yl)-4-bromophenol. The synthesis method comprises the following three steps of reaction: (1) glycosylation reaction; (2) aromatic cyclization reaction; (3) protecting group removal reaction. The yield of each step of reaction in the synthesis method can reach the medium level or more and even up to more than 90 percent, the reaction conversion rate of materials with high prices or preparation costs is relatively high, the total yield of the three steps canreach 37 percent, moreover, the reaction condition is mild, and the synthesis method is easy to implement. Furthermore, the step of glycosylation reaction and the step of protecting group removal reaction in the synthesis method can be applied.
