  • Koenigs–Knorr Glycosylation Reaction Catalyzed by Trimethylsilyl Trifluoromethanesulfonate
    作者:Yashapal Singh、Alexei V. Demchenko
    DOI:10.1002/chem.201805527
    日期:2019.1.28
    The discovery that traditional silver(I)‐oxide‐promoted glycosidations of glycosyl bromides (Koenigs–Knorr reaction) can be greatly accelerated in the presence of catalytic trimethylsilyl trifluoromethanesulfonate (TMSOTf) is reported. The reaction conditions are very mild that allowed for maintaining a practically neutral pH and, at the same time, providing high rates and excellent glycosylation yields
    据报道,传统的氧化银(I)促进的糖基溴的糖苷化(Koenigs-Knorr 反应)在催化三氟甲磺酸三甲基硅酯(TMSOTf)的存在下可以大大加速。反应条件非常温和,可维持几乎中性的 pH 值,同时提供高速率和优异的糖基化产率。此外,还记录了一系列差异保护的糖基溴之间不寻常的反应趋势。特别是,在这些条件下,苯甲酰化的α-溴化物比其苯甲酰化的对应物更具反应性。
  • Characterization of the Isochromen-4-yl-gold(I) Intermediate in the Gold(I)-Catalyzed Glycosidation of Glycosyl ortho-Alkynylbenzoates and Enhancement of the Catalytic Efficiency Thereof
    作者:Yugen Zhu、Biao Yu
    DOI:10.1002/anie.201103409
    日期:2011.8.29
    Gold standard: The title gold complex (see scheme) was characterized unambiguously as an important intermediate in the title reaction. Protonolysis of this vinyl gold(I) complex was critical for regeneration of the active gold(I) species for the catalytic cycle, and use of a protic acid co‐catalyst significantly lowered the required catalyst loading to 0.5 mol %.
    金标准:标题金络合物(参见方案)被明确表征为标题反应中的重要中间体。该乙烯基金(I)配合物的质子分解对于活性金(I)物种在催化循环中的再生至关重要,并且使用质子酸助催化剂可将所需的催化剂负载量大大降低至0.5 mol%。
  • Stereodirecting Effect of C3-Ester Groups on the Glycosylation Stereochemistry of L-Rhamnopyranose Thioglycoside Donors: Stereoselective Synthesis of α- and β-L-Rhamnopyranosides
    作者:Jin-Cai Lei、Yu-Xiong Ruan、Sheng Luo、Jin-Song Yang
    DOI:10.1002/ejoc.201901186
    日期:2019.10.9
    tuning effect of C3‐ester groups on the glycosylation stereochemistry of Lrhamnopyranose (L‐Rha) ethyl thioglycosides is described. The 3‐O‐arylcarbonyl or levulinoyl carrying L‐Rha thioglycosides undergo highly α‐selective glycosylation while the glycosylation of the 3‐O‐4‐nitropicoloyl and 2‐pyrazinecarbonyl L‐Rha thioglycosides displays β‐stereoselectivity
    描述了C3-酯基团对Lrhamnopyranose(L-Rha)乙基硫代糖苷的糖基化立体化学的调节作用。带有L-Rha硫糖苷的3-O-芳基羰基或乙酰丙酰基经历高度α-选择性糖基化作用,而3-O-4-亚硝基甲酰基和2-吡嗪羰基L-Rha硫糖苷的糖基化表现出β-立体选择性

    from the corresponding glycosyl bromides, are shown to be excellent donors in glycosylation reactions. Both armed and disarmed donors were prepared and reacted smoothly with a series of glycosyl acceptors. Coupling proceeded in high yields, with activation of the donor achieved using a range of promoters, and also displayed unusually high selectivity. In addition these novel systems offer the potential

    rapidly synthesize sugar phosphates. Compared with chemical synthesis, enzymatic (kinase) routes to sugar phosphates would be attractive for this application. This work focuses upon the development of a high-throughput colorimetric galactokinase (GalK) assay and its application toward probing the substrate specificity and kinetic parameters of Escherichia coli GalK. The demonstrated dinitrosalicylic
    体外糖随机化(IVG)技术取决于快速合成糖磷酸酯的能力。与化学合成相比,酶促(激酶)途径转化为糖磷酸酯对于该应用而言将是有吸引力的。这项工作专注于高通量比色半乳糖激酶(GalK)检测方法的开发及其在探测大肠杆菌GalK的底物特异性和动力学参数方面的应用。证明的二硝基水杨酸测定法也应普遍适用于多种糖加工酶。[反应:看文字]
