    O- and N-Sulfations of Carbohydrates Using Sulfuryl Imidazolium Salts
    摘要:
    A series of sulfuryl imidazolium salts (SISs) were prepared and examined as reagents for incorporating trichloroethyl-protected sulfate esters into carbohydrates. The SIS that contained a 1,2-dimethylimidazolium moiety (SIS 9) proved to be a superior sulfating compared to SISs bearing no alkyl groups or bulkier alkyl groups on the imidazolium ring. Difficult O-sulfations that required prolonged reaction times and a large excess of the SIS bearing a 1-methylimidazolium group (SIS 5) were achieved in high yield using less than half the amount of SIS 9 in less time. Certain N-sulfated compounds that were practically inaccessible using SIS 5 were obtained in excellent yield using SIS 9.

    摘要:
    尽管他莫昔芬是治疗和预防雌激素依赖性乳腺癌的成功药物,但其使用因子宫内膜癌的低发病率而受到限制。人羟基类固醇磺基转移酶 2A1 (hSULT2A1) 催化他莫昔芬的 α-磺氧基代谢物的形成,该代谢物对 DNA 具有反应性,这与其致癌性有关。此外,hSULT2A1 在类固醇激素(如脱氢表雄酮 (DHEA) 和孕烯醇酮 (PREG))的代谢中发挥作用。 hSULT2A1 在类固醇激素代谢和产生他莫昔芬反应性代谢物中的这些作用使我们检查了它与他莫昔芬及其几种主要代谢物的相互作用。我们假设他莫昔芬的代谢物可以通过直接抑制或作为酶的替代底物来调节 hSULT2A1 的催化活性。我们发现 4-羟基-N-去甲基他莫昔芬 (endoxifen) 是 hSULT2A1 催化的 PREG 和 DHEA 硫酸化的有效抑制剂,Ki 值分别为 3.5 和 2.8 μM。在 hSULT2A1 催化的 PREG 硫酸化中,4-羟基他莫昔芬

  • Synthesis of zearalenone-16-β,D-glucoside and zearalenone-16-sulfate: A tale of protecting resorcylic acid lactones for regiocontrolled conjugation

    The development of a reliable procedure for the synthesis of the 16-glucoside and 16-sulfate of the resorcylic acid lactone (RAL) type compound zearalenone is presented. Different protective group strategies were considered and applied to enable the preparation of glucosides and sulfates that are difficult to access up to now. Acetyl and p-methoxybenzyl protection led to undesired results and were shown to be inappropriate. Finally, triisopropylsilyl-protected zearalenone was successfully used as intermediate for the first synthesis of the corresponding mycotoxin glucoside and sulfate that are highly valuable as reference materials for further studies in the emerging field of masked mycotoxins. Furthermore, high stability was observed for aryl sulfates prepared as tetrabutylammonium salts. Overall, these findings should be applicable for the synthesis of similar RAL type and natural product conjugates.

    本文提出了合成16-葡萄糖苷和16-硫酸盐的可靠程序,这是一种属于雷斯酸内酯(RAL)型化合物的玉米赤霉醇。考虑到不同的保护策略,并将其应用于合成难以获得的葡萄糖苷和硫酸盐。乙酰基和p-甲氧基苄基保护导致不良结果,被认为是不适当的。最后,三异丙基硅基保护的玉米赤霉醇作为中间体,首次成功用于合成相应的霉菌毒素葡萄糖苷和硫酸盐,这些物质作为参考材料对于新兴领域中的隐蔽霉菌毒素研究非常有价值。此外,作为四丁基铵盐制备的芳基硫酸盐表现出高稳定性。总的来说,这些发现应该适用于合成类似的RAL型和天然产物结合物。

Two approaches were developed for the synthesis of hydroxyphthioceranic acid (4), its polypropionate part, thereby establishing the absolute stereochemistry of the C17 hydroxyl function to be of (R)-configuration. Subsequently, 4 was regioselectively connected to the trehalose core and after selective sulfation and a final

    The chemical sulfation of β-resorcylic acid esters was investigated by applying state of the art procedures for the synthesis and deprotection of 2,2,2-trichloroethyl protected sulfates as appropriate intermediates. The selectivity of monosulfation was studied and reaction optimization was performed considering the effect of the solvent, different bases as well as the sulfation reagent itself. Finally

    Protected sulfate groups may be used as an alternative tool to provide sulfate esters at hydroxyl and amino groups, particularly on complex glycans. We examined 2,2,2-trichloroethoxysulfation at the mono-, di-, and trihydroxyl groups of saccharide moieties to show regioselective sulfation. We found some side reactions including inter- and intramolecular nucleophilic reactions with 2,2,2-trichloroethoxysulfates

    of enol sulfate esters from α-aryl aldehydes is described. This method involved the stereocontrolled enolization of a carbonyl group with DBU or t-BuOK followed by trapping with a reactive sulfuryl imidazolium salt, providing the corresponding styryl enol sulfate esters in good to excellent yields and stereoselectivities. This method was applied to the first total synthesis of the enol sulfate natural
