  Design and Synthesis of 2‘-Deoxy-2‘-Fluorodisaccharides as Mechanism-Based Glycosidase Inhibitors That Exploit Aglycon Specificity

  摘要：

  Stable, aglycon-specific inactivators of glycosidases have considerable potential as fools in the study of mechanisms of oligosaccharide processing, and possibly as avenues toward new therapeutics. Glycosidases for which the rate-determining step with the natural substrate is the hydrolysis of the glycosyl-enzyme intermediate are shown to be inactivated by the 2'-deoxy-2'-fluoro derivative of this substrate. Thus Agrobacterium faecalis beta-glucosidase is inactivated by 2'-deoxy-2'-fluorocellobiose according to inactivation parameters of k(i) = 0.018 min(-1) and K-i = 20 mM. Inactivation is shown to occur via the accumulation of the same 2-deoxy-2-fluoroglycosyl-enzyme intermediate as that formed using activated 2-deoxy-2-fluoroglycosides by identification of the labeled peptide in proteolytic digests. Thus, interactions between the enzyme and the sugar aglycon provide sufficient transition state stabilization to allow formation and trapping of the glycosyl-enzyme. beta-Glucocerebrosidase, a beta-glucosidase specific for hydrolysis of glucocerebrosides, is not inactivated by 2'-deoxy-2'-fluorocellobiose, thereby demonstrating the aglycon specificity of this class of inactivator.

  使用氟化氙方便地合成1,2-二氟-1,2-二脱氧己糖

  摘要：

  已经显示了在BF 3存在下使用XeF 2将氟添加到乙酰化的缩醛中的双键上的方法，为合成乙酰化的1、2-二脱氧-1、2-二氟糖提供了便利的途径。该试剂主要从受阻最小的一侧进攻双键，形成顺式加合物，但该反应还提供了其他异构体，这些异构体已通过色谱法分离，其立体化学由19F NMR光谱。所提出的反应机理涉及试剂对C-2的初始亲电子攻击，然后是对C-1的亲核攻击。加合物的脱乙酰基得到1,2-二脱氧基-1,2-二氟糖，这在生化研究中是有意义的。通过选择性水解1，2-二脱氧-1，2-二氟-1-岩藻糖的异头氟原子来制备结晶的2-脱氧-2-1-岩藻糖。

  ABSTRACT The reaction of D-glucal and its derivatives with the electrophilic N-F-fluorination reagents F-TEDA tetrafluoroborate and triflate was studied by means of 19F NMR spectroscopy. In all cases mixtures of 2-deoxy-2-fluoro-D-gluco- and -D-mannopyranose derivatives were formed, the ratio of which was dependent on the nature of the O-protecting groups. Concerning the products arising from the direct

  摘要利用19F NMR光谱研究了D-葡萄糖及其衍生物与亲电NF-氟化试剂F-TEDA四氟硼酸酯和三氟甲磺酸酯的反应。在所有情况下，均形成2-脱氧-2-氟-D-葡萄糖-和-D-甘露吡喃糖衍生物的混合物，其比例取决于O-保护基团的性质。关于直接通过双键添加试剂产生的产物，D-葡萄糖构型的化合物（13-20）通常显示出比其D-甘露聚糖对应物（21-28）更高的水解速率。仅当形成单个端基异构体（例如2,4-二硝基苯基糖苷29e / 37e和二糖氟化物35d / 43d）或过氧乙酸酯（例如29f / 37f）时，才能实现产品分离。
