• Synthesis of Phenolic Glycosides: Glycosylation of Sugar Lactols with Aryl Bromides via Dual Photoredox/Ni Catalysis

  Multifarious sugar lactols were efficiently transformed into the corresponding phenolic glycosides by treating with aryl bromides in acetonitrile with Ir[dF(CF3)ppy]2(dtbbpy)(PF6) as a photocatalyst under visible light irradiation. Both pyranoses and furanoses or even disaccharide could all suffer this glycosylation protocol under mild reaction conditions. A variety of phenyl glycosides can be produced

  通过在可见光下用Ir [dF（CF 3）ppy] 2（dtbbpy）（PF 6）作为光催化剂在乙腈中用芳基溴化物处理，将多种糖乳糖醇有效地转化为相应的酚类糖苷。在温和的反应条件下，吡喃糖酶和呋喃糖酶甚至二糖都可能遭受这种糖基化方案的影响。可以以中等到良好的产率（高达93％的产率）生产各种苯基糖苷，并且该方案的克级工艺也得到了很好的确立。

  Reaction of phenyl-trimethylsilylethers (3) with 1-O-trimethylsilyl-2,3,4,6-tetra-O-acetyl-D-glucoside (1) (anomeric mixture) yields almost exclusively the aryl-β-glucosides (4) in the presence of catalytic amounts of TMS-triflate at 20°C, whereas (3) and 1-O-trimethylsilyl-2,3,4,6-tetra-O-benzyl-D-glucoside (2) gives mainly the aryl-α-glucosides (8).

  electron-withdrawing, and hindered phenols. The reaction is likely to proceed through a seven-membered ring intermediate, wherein the palladium catalyst coordinates to both C(1)-trichloroacetimidate nitrogen and C(2)-oxygen of the donor, blocking the α-face. As a result, the phenol nucleophile preferentially approaches to the top face of the activated donor, leading to formation of the β-O-aryl glycoside.

  立体选择性合成β- O-芳基糖苷的通用方法的开发，该方法利用阳离子钯（II）催化剂的性质代替C（2）-酯导向基团的性质来控制β-选择性描述。这种β-糖基化反应具有很高的非对映选择性，并且需要2–3 mol％的Pd（CH 3 CN）4（BF 4）2在室温下活化糖基三氯乙酰亚氨酸酯供体。目前的方法已应用于具有在C（2）位置掺入非定向基团的d-葡萄糖，d-半乳糖和d-木糖供体，以提供O芳基糖苷具有良好至极好的β选择性。另外，它的应用广泛用于给电子，吸电子和受阻酚。该反应可能通过七元环中间体进行，其中钯催化剂与给体的C（1）-三氯乙亚氨酸氮和C（2）-氧均配位，从而阻断了α-面。结果，苯酚亲核试剂优先接近活化的供体的顶面，导致β- O-芳基糖苷的形成。

  We report the efficient O-glycosidation of glycosyl bromides with therapeutically relevant acceptors facilitated by silver N-heterocyclic carbene (Ag-NHC) complexes. A set of four Ag-NHC complexes was synthesized and evaluated as promoters for glycosidation reactions. Two new bis-Ag-NHC complexes derived from ionic liquids 1-benzyl-3-methyl-1H-imidazolium chloride and 1-(2-methoxyethyl)-3-methylimidazolium chloride were found to efficiently promote glycosidation, whereas known mono-Ag complexes of 1,3-bis(2,4,6-trimethylphenyl)imidazolium chloride and 1,3-bis(2,6-di-isopropylphenyl)imidazolium chloride failed to facilitate the reaction. The structures of the promoters were established by X-ray crystallography and these complexes were employed in the glycosidation of different glycosyl bromide donors with biologically valuable acceptors, such as estrone, estradiol, and various flavones. The products were obtained in yields considered good to excellent, and all reactions were highly selective for the 13 isomer regardless of neighboring group effects. (C) 2011 Elsevier Ltd.
